help a ftm out please

Desirea • Mrs.Gutierrez 2017💍😍 mommy of soon to be two! 💙💜
For 2 days now I have been having contractions like crazy along with havening to poop but nothing coming out, well today I thought I was going to get a break and went to lay down for a nap and for 15 mins I have been having severe cramping in my belly and it's now happening in my back. Anyone know what I should do?
