Is this normal? 15 weeks pregnant.?

yes it is normal to have a hard stomach at this stage. if your stomach is getting larger as the day goes on it is more than likely bloating this is very common in pregnancy. on your first baby you wont notice the baby move till 20-22 weeks pregnant it was more than likely gas but if this is your 2nd baby or more you will notice the baby move at about 15 weeks this is because your body knows what it feels like so you notice it earlier in pregnancy
