is my baby coming???

Alana
So this is my first baby and I'm clueless as to how it will feel when I go into labor or what starts to happen as I approach labor, because this is not something I have experienced before. I have been up all night and I was just sitting there and watching my belly move and all the sudden got a sharp sudden pain in what feels to be my vagina/ pee hole lol. It feels like ripping and as he moves and the pains come and go it's giving me a sensation that feels as if one of his feet could pop out in that moment. Idk what it is but it hurts. Help!!! 
Btw I am 39 weeks and 3 days 😩
