Can't tel if I'm having.contractions?! FTM

Katrina Rose • Having a baby with the most amazing man on this earth. Been together 5 years! Due February 16th 2017. Our first baby .

I'm a FTM I'm 37weeks 4days, I've been experiencing these very sharp pains that my whole tummy tightens right up. Then I'm feeling a lot of pressure down there. I'm not sure what's going on.

Any ideas?
