Contractions or baby moving?!

Ladies ftm here, this might sound completely off the wall. I have had Braxton Hicks contractions and this I nothing like it. It keeps getting stronger but it feels like my baby is trying to stretch out in the womb and escape. While it can feel tightening I feel like she's pushing off the sides of the womb. My stomach is as hard a rock, and I've been having cramping. I do the want to think I'm looney and going into labor when I'm really just having a strong baby movement. It drives me nuts not knowing for sure... Anyone else have this?! Do I just need to relax?
