pregnant and not sure what to do (venting)

So i just found out im pregnant from my BD but we are not together just had an oopsies. I genuinely thought he did not 💦 in me as he has more so made it clear that he doesnt want anymore and I didnt think to even ask if he did. Welp couple weeks go by I tested the other night took multiple and im pregnant. No one really knows we have been fucking around again and certainly wasnt expecting to get pregnant so fast we have a 3 year old together but separated almost 2 years ago 😅 unsure what to do just needed to vent
