😔 just found out I'm pregnant

Sooooooo lm pregnant... the man is not even my bf, he was just someone I've been attracted to for the longest. It happened the first time we had sex after 7 years of waiting. He already has a baby with someone else and he's going through custody battle with his ex. I'm sitting here all by my self without him knowing that I just found out. I don't know what to do... before we even had sex we had both agreed that we were just going to take things really slow cuz we both aren't ready to jump in a relationship. I wasn't expecting this to happen I'm just lost for words... I also just got accepted to a cal state and would start in August. My mom so far does not support that I got pregnant...

I'm also not a kid I'm 28...

My mom basically doesn't want me to be a single parent and have to deal with someone who already had a kid his self.
