I felt mine at 18 weeks , it got stronger at 19 & then at 20 it was constant & strong.
I'm 18 weeks 4 days and I get little flutters that I think are the baby, I'm not sure though. A lot of people don't feel baby until around 20 weeks.
It is different for everyone. Some women feel the baby as early as 16 weeks, some as late as 24 weeks. I felt my son at 20 weeks because he would kick my bladder. I felt him on my stomach at 22 weeks.
You can, just depends on your body. I felt my baby move at 16 weeks and this is my first. Some Dont feel until 20+ weeks.
