I felt my son's first movement around 16 weeks of pregnancy. But if this is your first pregnancy, you may not feel your baby move until closer to 25 weeks. I was more likely to feel baby moved when I was in a quiet position, either sitting or lying down. I just felt a few flutters every now and then.
Our son was usually most active between 9 p.m. and 1 a.m., right as I was trying to get to sleep. Sometimes bumps were big enough that I could see my stomach jumped.
Here is a guide to your baby's possible movements.
Week 12: Your baby should start to move, but you probably won't be able to feel anything, because the baby is still so small.
Week 16: Some pregnant women will start to feel tiny
butterfly-like flutters. The feeling might just be gas, or it might be
the baby moving.
Week 20: By this point in your baby's development, you may start to really feel your baby's first movements, called "quickening."
Week 24: The baby's movements are starting to become more established. You might also begin to feel slight twitches as your baby hiccups.
Week 28: Your baby is moving often now. Some of the kicks and jabs may take your breath away.
Week 36: Your uterus is getting crowded as the baby grows, and movements should slow down a bit.
