Worried, please help

Hi everybody, I was hoping to get some help or reassurance or something. I’m 14 weeks pregnant and I’m worried something is wrong. I’m having a lot of pressure and feel like I have to poop, which I have been constipated, so it could be that. But my vagina was feeling weird, so I stuck a finger in and it feels like something is bulging out of the wall of my vagina, and it feels big. I can’t even get my finger up to where my cervix is.

Could I be losing the baby? Should I go to the hospital, or wait and call my OB in the morning? Has anybody had this before?

I’m sorry, I’m just so scared guys
