Mistakes Pregnant Women Make in The First Trimester

Eat for Two

I’m not exactly sure where the phrase “eating for two” originated from, but within it is the assumption that pregnant women get to eat whatever they want and as much as they want. Yes, you need to eat more during pregnancy, but it’s not by that much, if anything, during the first trimester.

During the first trimester your caloric intake doesn’t need to increase, however, during the second trimester and the third the increase is around 300-500 calories.

Instead of focusing on counting calories I would focus on:

Real Food for Pregnancy by Lily Nichols is my all-time favorite pregnancy book about food. I highly recommend it!

TIP:  Try these energy balls for pregnancy to keep energy levels up and morning sickness symptoms at bay. They’re so delicious! I prefer to eat them frozen.

Eat Too Little

Another one of the mistakes pregnant women make in the first trimester is eating too little. Prior to pregnancy the consequences of skipping a meal may have been insignificant, but not eating enough, frequently enough, during pregnancy, is a big trigger for morning sickness.

To minimize morning sickness symptoms, it’s important to eat high quality foods paired with protein every 2-3 hours.

If you follow these tips you will minimize morning sickness symptoms, but also increase energy and of course, help your baby to grow healthy and strong.

Here’s a list of snack ideas that can help alleviate morning sickness.

Go to the Doctor Too Early

With my first pregnancy, as soon as I began experiencing signs of early pregnancy and got a positive pregnancy test, I called my OBGYN. I kept asking myself, “What do I do?”. Hahaha…

I think I was so overwhelmed, and since I’m such a “doer” I needed to do something to do make me feel at ease.

The reality is, there’s really nothing to be done so early in pregnancy. There’s no rush, no emergency. When you get a positive pregnancy test result, it’s too early for an ultrasound, and there isn’t anything your care provider can do for you.

Of course there are always exceptions, for example, someone that is using reproductive technologies, has health problems, or is a high risk pregnancy.

It is perfectly fine to enjoy the first weeks of pregnancy and do nothing! Buy a pregnancy journal or start one on your own with pregnancy journal prompts, spend time in nature, and begin taking a prenatal vitamin with folate. I recommend the Garden of Life prenatal, which is listed on my pregnancy resources. These three things would be a great place to start!

Go to the Doctor Too Late

On the other hand, another one of the mistakes pregnant women make in the first trimester is to go to the doctor too late. And when I say doctor, I mainly mean midwives or care providers that have small, limited practices.

If you have your heart set on using a midwife that has a small homebirth practice, you probably should call her for an interview or consultation as soon as you pee on a stick. There’s a local homebirth midwife in my area and I know she’s turned clients away solely because she was booked up.

If you’re planning on using a big box OBGYN (just coined that term, ladies) there’s absolutely no need to call early. Trust me, they’ll take you!

PS – Here’s a great post about how to know if it’s time to fire your OBGYN. Keep this information in mind when searching for the right care provider.

Expect an Ultrasound

Another one of the mistakes pregnant women make in the first trimester is to expect an ultrasound.

In my opinion, ultrasounds should only be used when medically necessary. If there is no medical reason to receive an ultrasound, I would not partake.

The reason I say this is because the risks of ultrasound have not been fully researched. In one study it has been found that ultrasound increases the chance of left-handedness. It’s not that left-handedness is bad, it’s that something about ultrasound is altering our children’s bodies. That concerns me!

Even the FDA cautions against it!

PS – After having repeated miscarriages, for future pregnancies I was all about ultrasounds. At that point I had an MTHFR diagnosis and ultrasounds were apart of my pregnancy protocol per my neonatologist. Seeing my baby growing healthy and strong was such a relief. I get the draw of ultrasounds! All I’m saying is to use ultrasounds with wisdom and discernment just as you would taking any supplement or medication during pregnancy.

Announce the Pregnancy

Announcing a pregnancy during the first trimester is a very personal choice, but I think most women don’t consider what they’re getting into with an early announcement, especially if they’ve never experienced a miscarriage before.

When I had my first miscarriage I was shocked! I thought that sort of thing would never happen to me. Others? Perhaps. But not me.

After I realized I was miscarrying, I was grateful that I had not announced my pregnancy on social media. I would have hated having to announce my miscarriage on there as well. It was difficult enough for me to contact the friends and family we had shared the pregnancy news with that the pregnancy had ended.

However, other women, perhaps the more extroverted ones, do not find announcing a pregnancy in the first trimester to be a problem. In fact, they report quite the opposite. They realize that an early public pregnancy announcement could translate to a public miscarriage announcement. Some women are grateful for the outpouring of support and find comfort grieving in public.

My advice? Wait until closer to the second trimester to announce a pregnancy. By that time you’ve likely heard the heartbeat and I’ve always heard that once you hear the heartbeat the chance of miscarriage goes way down. But of course, do what you most feel comfortable doing. There’s no manual for this sort of thing.

SIDE NOTE:  Just for fun, here is my first pregnancy announcement at 12 weeks, the next at 10 weeks pregnant, and the grand finale, my third pregnancy announcement at 10 weeks.

Share Belly Photos on Social Media

Seeing belly photos on social media prior to the second trimester always makes me giggle. Unless you’re carrying twins, the uterus isn’t large enough to be “showing” enough to warrant Facebook documentation of said pregnancy.

Likely, you’re just documenting bloating or a food baby. LOL!

Exhibit A: My youthful, skinny, tight body. RIP abs. See how nothing really happens until the second trimester?

If you do share pregnancy belly photos in the first trimester, I get it, I do. To me it shows that you are VERY excited about the changes within you, which is super sweet.

PS – I think this photo is hilarious.

Overdo It

WARNING:  If you are a type A, overachiever, modern, American woman, etc. you are extremely susceptible to overdoing it during pregnancy.

Many of us have the misconception that we need to be all things and do all things, even on into pregnancy and parenting. This is simply impossible.

To avoid burnout, schedule “self care” activities in your calendar. Just like it’s important to take a prenatal vitamin every day, taking time to “not be productive”, but taking care of yourself is just as or even more important.

Listen to your body, rest or nap when you need it. And if it helps, remind yourself that, today, you grew a pair of ears. And sometimes, that is enough (and is amazing).

TIP: Here are some general sleep tips to follow at any point in pregnancy to help you sleep better. I hope it helps!


I live in a very consumer driven society, and likely, you do too.

For example, after an initial pregnancy visit with my OBGYN I started receiving baby related marketing materials in the mail. (How did they get my information??!! And just for the record, ViaCord, I did not want your blood banking services. I always planned for delayed cord clamping instead.)

If you are expecting, you likely feel pressure to buy the latest and the greatest baby gear. The underlying message sent to new moms is the way to prepare for a baby is to buy baby things.

Sure, preparing for a baby is partly gathering gear, but it’s so much more than that. Baby gear, clothes and snot suckers will fade away. But your birth, and how you were made to feel during it, will stick with you forever.

Don’t believe me? Read the comments on my post about how to get through transition without an epidural.

Baby gear is necessary, but make sure buying baby things is balanced with quality pregnancy, childbirth and postpartum education and support.

In the first trimester, make sure to start researching childbirth resources and options in your area. Contacting a local doula is a great first step! Doulas are a wealth of information.

Just because you didn’t show in your first trimester doesn’t mean ALL women don’t. The uterus can expand at different rates for different women, and different body types, etc all affect this. To say that IF they have a bump in the first trimester is “just documenting bloating or a food baby. LOL!” is not necessarily true, and it sounds condescending and misinformed. Anyways I stopped reading after that, honestly I can’t even believe I read that far. This entire blog post is so negative and condescending.

Mom of 4

Thursday 13th of January 2022

I’m sorry but as a mother of 4, this is a lot of poor information. I had ultrasounds with my first 3 at 4 weeks, shared my pregnancy with loved ones because who wants to experience loss alone? Had Drs appts right away for blood work and to confirm the pregnancy. And who says it’s wrong to share belly pics? By #4 I had a bump at 10 weeks. This is part of the problem with all the pressure new moms feel. This article really made me sad. So much bad information.

Ultrasounds are completely safe for you and the baby. It’s Doppler you have to be a little more worried about. Coming from an ultrasound technologist. Otherwise thank you for the other information:)
