Kinda scared

Lizzy
I'm 12 weeks 
And I reading every bodies stories and hearing how they can feel the baby move and stuff. All I feel is cramping and side pains. I might have felt some pulsing the other day. But that's about it! This is my first successful pregnancy. All the others were ectopic pregnancies. So I'm always worried I know I shouldn't stress my self out but lord knows I do smh.
