Baby movements

I haven't felt BB movements, now that I'm in my 19-20 weeks.
I hope this is normal as references says the movements should be felt starting 20weeks.

When should I start to feel my baby move?

You probably won't feel your baby kick until sometime between 16 and 22 weeks, even though he started moving at 7 or 8 weeks and you may have already witnessed his acrobatics if you've had an ultrasound.

Veteran moms tend to notice those first subtle kicks — also known as "quickening" — earlier than first-time moms. (A woman who's been pregnant before can more easily distinguish her baby's kick from other belly rumblings, such as gas.)

Your build may also have something to do with when you'll be able to tell a left jab from a hunger pang. Thinner women tend to feel movement earlier and more often than women who carry more weight.
