Feel like my baby is going to just fall out...

Ugh, sorry I am full of questions today! I know its not possible but let me explain! I'll be 22 weeks tomorrow, and lately I've been getting jabs to the cervix, nothing painful just odd! (I know thats normal) No cramping/contractions. No bleeding, no more discharge than usual and it hasn't changed. But the past few times I've gone to the bathroom I feel like my little guy is going to just fall right out. Is that normal? It's almost like a light pressure different from when I get a light jab to the cervix. Should I go get checked out or am I having first time momma worries?
