The baby is lying inside an amniotic sac, a bag formed of membranes filled with fluid. A placenta is starting to form and attaching to the inside of your womb (uterus) so that it can deliver nutrients and oxygen from your blood stream to your baby. The baby's heart is now beating at 150-180 beats per minute.
You won't have a bump for a while yet, but at week 7 your womb (uterus) is already expanding to accommodate your growing baby. As this happens, the tissues supporting your womb (ligaments) will stretch and you may feel mild cramps or twinges in your tummy.
Meanwhile, your womb is now about the size of a lemon, while your baby is the size of a grape and growing very quickly. If it's your first pregnancy, you may not start looking pregnant until around week 12.
It's unlikely that you'll have a baby bump at seven weeks, but your body is changing even at this early stage. Your stomach muscles are continuing to relax and your uterus is expanding. By week seven it's said to be about the size of a lemon and will continue to grow to cater to your growing baby.
When does your belly start feeling hard during pregnancy? This varies, but it's usually during your second or third trimester. As your uterus grows, it eventually pushes against your abdominal wall, making your abdomen feel firm. The muscles and ligaments around your uterus stretch, too, which can cause mild cramping.
7 weeks pregnant: What to expect
You may start to feel bloated and your breasts may start getting bigger. Your baby is growing, too. Baby's head and face are developing and tiny hands and feet are sprouting. Your fatigue may be intense right now.
Baby flutters during early pregnancy
If you're feeling anything fluttering down in your tummy around this time, it's possible that your baby is grooving around in there. Baby's kicks are also called quickening. It may be difficult to tell at first if what you're feeling is your baby or gas.
"Not everyone experiences morning sickness, just like not everyone gets motion sickness." If you don't experience morning sickness, your body just might be better able to handle the rapid rise in levels of human chorionic gonadotropin (hCG), estrogen, and other hormones that come during the first trimester.
A fetal heartbeat may first be detected by a vaginal ultrasound as early as 5 1/2 to 6 weeks after gestation. That's when a fetal pole, the first visible sign of a developing embryo, can sometimes be seen. But between 6 1/2 to 7 weeks after gestation, a heartbeat can be better assessed.
You at 7 weeks
You're probably feeling tired. Your breasts might feel sore and enlarged, and you may need to pee more often than usual. You may start to feel sick or tired, or have other minor pregnancy problems for a few weeks around this time.
Fortunately, this is normal. It's a signal from your body to slow down and give it time to adjust to the incredible changes happening inside. Hormone changes play a big role in making you feel tired, especially the hormone progesterone. This hormone rises sharply in the first trimester.
More than 80% of miscarriages occur within the first 12 weeks of pregnancy. After 12 weeks, the rate decreases rapidly (Dante et al, 2013; Houry and Salhy, 2014).
Most miscarriages occur before the 12th week of pregnancy. Signs and symptoms of a miscarriage might include: Vaginal spotting or bleeding. Pain or cramping in your abdomen or lower back.
Be especially careful during your first trimester. Watch the Heat. A high body temperature can harm your baby, especially in the first weeks of your pregnancy. Limit sauna and hot tub use to less than 10 minutes.
Possible safety concerns
Eating watermelon during pregnancy is generally considered safe. However, this fruit is moderately rich in carbs and low in fiber, a combination that can cause blood sugar levels to spike ( 1 ).
Good news: getting your hair dyed while pregnant is considered safe, especially in the second and third trimesters. Since most hair dyes have little contact with your scalp, the chance of any chemicals reaching your bloodstream, and therefore your baby, is low.
At the 7 weeks scan, only a gestational sac and yolk sac may be seen. It's still very early in the pregnancy. If there are concerns, you may be asked to return for another scan in 7 to 10 days to check on the embryo's development.
Baby at 7 weeks is beginning to look more and more like, well, a baby, with arms and legs that look a little less paddle-like with webbed hands and feet. Baby is developing recognizable facial features like ears, eyes, nostrils and a mouth, which are all becoming more defined.
The embryo is about 1 cm long from head to tail – about the size of a coffee bean. Body parts are usually out of proportion at this stage. The face is forming around the mouth. The embryo has large eyes, ear buds and a wide forehead.
