Pregnancy Checklist At 6 Weeks Pregnant

Prepare for Your First Prenatal Visit

Is your first prenatal visit coming up soon? It can be a momentous occasion: You’ll talk to your doctor or midwife about your pregnancy, and you may have an ultrasound and see your baby’s tiny heart beating! Be prepared to discuss your health history, your family’s medical history, and your habits. If you haven’t yet chosen a doctor or midwife to care for you during your pregnancy, go ahead and find someone so you can get started on your prenatal care. You can always switch to another caregiver later if you want.

Research Foods to Avoid During Pregnancy

During pregnancy, it’s better to skip some foods completely. You also need to take a few precautions like cooking them thoroughly. Talk to your doctor and find out what’s safe to eat and drink during pregnancy and what to avoid.

Learn About Prenatal Testing Options

There are screening tests that use blood samples and an ultrasound to determine the baby’s chances of having down syndrome or any other chromosomal differences. 

Make Sure Your Workplace Is Safe

Some jobs or hobbies can be hazardous to you and your developing baby. If you’re routinely exposed to chemicals and heavy metals like mercury or lead, inform at work and make some changes as soon as possible.

Try to Reduce Stress

Chronic stress isn’t good for you or your baby. Try to manage stress during pregnancy by surrounding yourself with positive people, taking breaks, doing yoga and listening to music or journaling. 

What To Ask Your Doctor?

Ask your doctor about what exercises and medicines are safe for you. Also, ask about weight gain and any diet changes that you need to make. You can also ask about your skincare routine.

Things To Note

At 6 weeks pregnant, you might hardly look pregnant. Even the 6th-week pregnancy symptoms which are a part of the first trimester are just beginning and some women may show no symptoms at all. However, it is important to seek medical help when needed and take care of the diet and health. For better understanding, track your pregnancy week by week.

A fetal heartbeat may first be detected by a vaginal ultrasound as early as 5 1/2 to 6 weeks after gestation.
