34 weeks and cramping

So I've been having cramp like pains (like vagina pain) for about two days now on and off , sometimes I'll notice a little bit of lower back cramping or period like cramps, I can still feel baby moving around I'm just getting nervous as  to why this is all the sudden. It feels like the baby is kicking my vagina hard sometimes as well (sorry for tmi ) thank you ladies in advance !
