Answer: When the symptoms of the first trimester such as nausea and vomiting, fatigue and a frequent urge to pee subside, many mums-to-be worry. They think that the lack of symptoms might mean something is wrong with their pregnancy. Usually though everything is just fine.
By 12 weeks of pregnancy, your baby is fully formed. All his essential organs, such as his heart, liver and kidneys are in place, and some organs are beginning to work for themselves. As you start your second trimester, it's as if everything settles down after the major changes and upheaval that your body has gone through during the past three months.
If all were not well with your pregnancy, you'd most likely have other symptoms such as brown vaginal discharge, bleeding and pain. Occasionally, there may be a problem without these warning signs (missed miscarriage) which may be picked up during a routine antenatal appointment.
Some women do have a feeling that something isn't right before a missed miscarriage is confirmed. But it's far more likely that your baby is still flourishing. If you haven't yet had your first antenatal scan, this should reassure you that your baby is fine.
Over the next three to four weeks, your baby will grow rapidly. Your uterus is getting bigger all the time, though you won't be aware of it for a while. After 13 weeks, if you press your tummy gently, you may be able to feel the top of your uterus (fundus) just above the pubic bone. Most women can't feel it, though, so don't worry if you can't.
At 16 weeks, your clothes will probably feel tighter and more uncomfortable around your waist. You may be aware of a slight bulge below your belly button even sooner than this.
At 18 weeks to 20 weeks, you’ll probably start feeling your baby’s movements. You will start getting gentle fluttering feelings (quickening) in your tummy.
It's only natural to worry at around 13 weeks of pregnancy, before your bump really starts to show. But if you're feeling very anxious, talk to your doctor.
Remember that the second trimester is a time of healthy, rapid growth for your baby. You will begin to relax and enjoy being pregnant, and feel more like your usual self.
