I been feeling something in my stomach all day not sure if its the baby or what FTM problems

if it feels like flutters its your little one kicking/ moving around

but I'll be 12 weeks tomorrow isn't it to early for me to feel it like I will feel a vibrating & then a swoosh & then it stop

Some people can feel the baby early depends on the person and body type

I feel little movements sometimes but at the bottom

if you are short waisted and the placenta is in the back of ur uterus you will feel more fluttering early in pregnancy. I felt it at 10 weeks
