Wtf 😳

So I got up to have my 4am bowl of cereal, was standing up to eat it in the kitchen and it felt like my son was hitting his head against my cervix or something! I really have no idea! But it felt VERY UNCOMFORTABLE and I literally had to hold my whoha because it felt like he was trying to come out or something! What's happening? 
I'm 36 weeks and 2 days. He's SO LOW!!!! Like reallly low ...
