7 Weeks Pregnant

Learn what's happening in week 7 of pregnancy and find out how your baby is developing.

Seven weeks into your pregnancy, there are a lot of things happening with you and your baby. At this stage, your baby is the size of a blueberry and is generating about one hundred new brain cells each minute. Your baby's brain and heart are becoming more complex and the kidneys are also developing. At seventh week of pregnancy, your achy and tingly breasts are growing faster than your baby's brain and your uterus has doubled in size.

What happens in your body in pregnancy week 7?

7 Weeks Pregnant

During pregnancy, your body experiences gradual changes. At seven-week of pregnancy, people around you can't really notice that you are pregnant. You may gain a couple of pounds, but you may also lose weight especially if you're experiencing morning sickness - one of the most common pregnancy symptoms at 7 weeks. You may also be experiencing other early symptoms of pregnancy.

Changes in Your Body at 7 Week Pregnant

Seven weeks in, you may be experiencing some of the most unpleasant signs of being pregnant, including nausea, fatigue, mood swings, bloating, cravings, headaches and tender breasts.

You may also need to pee more than usual, thanks to your increasing blood volume and the extra fluid being processed through your kidneys. You're probably not showing much at this stage, but you are more than likely feeling bloated and very pregnant. Pregnant women also find themselves craving foods they once thought were disgusting, which is completely normal. The mucus on your cervix is thickening and is forming a plug that will seal the entrance to your uterus until you give birth.

You may notice that you're beginning to lose your waistline, so this is the right time to start looking for comfortable maternity clothes.

If you're feeling sick and nauseated, keep in mind that all of these signs of pregnancy mean that pregnancy hormones are working overtime to support your growing baby.

Your Baby at 7 Week of Pregnancy

Your baby is growing and developing rapidly in the seventh week and is about the size of a blueberry.

Your baby is approximately an inch (2.54 centimeters) long by the end of week seven and weighs less than an aspirin. The facial features are beginning to come into focus, and the mouth, tongue, and eyes are forming.

At this point, your baby is developing its own blood type. The intestines and appendix are now fully formed, while the bones, muscles, and all essential organs continue to grow. Your baby’s tiny toes and fingers can already be seen in an ultrasound.

Technically, your baby is still considered an embryo that has something that looks like a small tail, which is actually an extension of her/his tailbone. The tail will disappear within a few weeks.

Pregnancy Week 7 Tips

If you have not chosen a doctor or midwife, now is the time to choose one. Make sure that you're eating the right foods and taking in the correct nutrients and medications. It's important to take prenatal vitamins with folic acid because everything you put in your mouth has a significant effect on your little one. At week seven of pregnancy, you may be suffering from morning sickness. This is one of the first symptoms of pregnancy which is caused by the increased amount of hormones in your body. Avoid being around people who are unwell and be cautious around certain animals as they can carry an infection which causes miscarriage, and cat litter trays which can cause toxoplasmosis, a parasitic infection.
