11 Weeks Pregnant: Symptoms, Baby Development and Expert Tips

When you're 11 weeks pregnant, you're almost at the final stretch of your first trimester—woohoo! That's about two months and three weeks along. Your baby is growing rapidly and becoming more active, and you might be noticing some changes in your body, too. Here’s what to expect at 11 weeks pregnant, from fetal development to how to manage common symptoms. 

Fetal Development  

At this point in your pregnancy, your baby’s development is speeding up. Your baby is about the size of a kamias—approximately 4.1 cm long, weighing around 7 grams. According to the American Journal of Obstetrics and Gynecology, it's a key time for fetal development: the head is still large, but the body is catching up. Fingers and toes are separating, hair follicles are forming, and tooth buds are beginning to develop under the gums. Meanwhile, external genitalia are forming—though it might be too early to throw that gender reveal party.  

Inside, major organs like the liver and pancreas are starting to function. The diaphragm is developing, which will eventually allow your baby to breathe. The baby can now stretch, kick, and even hiccup—though you won’t feel it just yet. 

Physical Changes and Symptoms in Your Body  

You might still be dealing with nausea, food aversions, fatigue, or mood swings due to hormonal changes. Bloating, increased vaginal discharge, and breast tenderness are also very normal. Some women even report diarrhea at 11 weeks pregnant, possibly triggered by hormonal changes or prenatal vitamins. But don’t worry! The Journal of Maternal-Fetal and Neonatal Medicine says these tummy issues are normal and usually resolve on their own.  

Excited to see your bump? For some, the 11 weeks pregnant belly is just starting to show. Others might not notice any change yet. Every pregnancy is unique, and factors like your body type or whether it’s your first pregnancy can affect when you show. 

Nutrition and Diet for 11 Weeks Pregnant  

Nutrition is your top priority. Eating well supports baby development and helps you manage symptoms. According to Williams Obstetrics, a diet rich in iron, calcium, and folic acid is essential for fetal growth and maternal health during this stage. Small, frequent meals can help with nausea. Stay hydrated and avoid foods that may irritate your stomach if diarrhea is an issue. 

Tips for a Healthy Pregnancy 

Staying healthy while 11 weeks pregnant requires ample rest, healthy eating and staying on top of your prenatal vitamins. 

Want to stay in the pink of health while growing a little one in your belly? Rest when you can, even a quick nap will help. Move your body gently  when your doctor gives the go signal; walking or prenatal yoga can feel really good. Don’t forget to take your prenatal vitamins daily and keep caffeine to a cup a day. And most importantly, avoid alcohol, smoking, and recreational drugs, and stay on top of your doctor visits. These trips are key to keeping you and bub on track.
