Understanding each stage of your baby's development

Being pregnant is an amazing adventure, though it can be overwhelming. But knowing the stages of fetal development and taking steps to stay healthy during pregnancy can help you stay prepared throughout your pregnancy.

The first trimester — The foundation of life

In the first trimester of pregnancy, which lasts about 13 weeks, your baby undergoes significant growth and development. It's important to have regular prenatal checkups to monitor your baby's progress.

During this time, major organs and body systems are starting to form, with the heart beginning to beat and tiny limbs starting to appear.

"During pregnancy, your body goes through changes like nausea, tiredness and hormonal shifts," says Jennifer L. Cutilli, MD, an OB/GYN physician at Main Line Health. "These symptoms are common and can be managed by staying hydrated, eating well and getting plenty of rest."

If you're feeling uncomfortable, talk to your healthcare provider for personalized advice and solutions.

The second trimester — Growth and movement

During the second trimester of pregnancy, which lasts 14 through 27 weeks, mothers-to-be often feel better as early symptoms subside and they gain more energy. This is also when they start feeling their baby's movements, strengthening the bond with their growing child.

The 20-week ultrasound is a milestone that many expecting parents look forward to. During this time, your baby's growth is in full swing with the development of features like eyebrows and eyelashes. At the ultrasound, you'll get a detailed look at your baby's progress and even find out the gender if you'd like.

While all of this is exciting, don't forget to take care of yourself. Make sure you're healthy eating and working in gentle exercise to make this time even better. And if you have any questions, talk to your doctor during your appointments.

The third trimester — Preparing for birth

During the third trimester of pregnancy, which lasts from week 28 until birth, your baby experiences rapid growth and important developments like brain and lung maturation. You may notice more movement as your baby reacts to sounds and light, creating a sense of anticipation for the upcoming birth.

"During this time, it's normal to experience backaches, swelling and fatigue as your body changes to accommodate your growing baby," says Dr. Cutilli. "Listen to your body and take care of yourself by continuing to exercise, drink water and eat well. All of these will help to ease any physical discomforts during pregnancy."

Maternal wellness — Taking care of yourself

While staying active and eating healthy are important through pregnancy, your mental and emotional wellness are also vital. Take care of yourself during pregnancy by making time to relax and seeking support when needed. Listen to your body and prioritize self-care by resting, staying hydrated and doing things that make you happy.

"Don't be afraid to ask for help from friends, family or professionals and reach out to your healthcare provider with any worries or questions," says Dr. Cutilli.

Seeking personalized care throughout your pregnancy

Pregnancy can bring unforeseen challenges, but it's normal to worry about complications like gestational diabetes or preterm labor. That's why it's important to have a proactive plan with your healthcare provider and openly discuss any symptoms during your check-ups.

Choosing your OB/GYN is essential for a smooth pregnancy experience. Look for a healthcare provider who respects your decisions, provides comprehensive care and is conveniently located.

Your OB/GYN can provide customized advice and treatments to help you and your baby stay healthy. Personalized care acknowledges your individual needs and choices, giving you comfort and confidence during your pregnancy. With the proper support, you can handle any obstacles with ease.
