More than friends

So I’ve been friends with this guy now for almost 2 years (we talk off and on here and there ) but like we never meet up or anything like that.so recently I’ve been more open and let him take me out as friends and eventually let him come to my home where we had amazing sex 🤦🏼‍♀️ all this week! he’s even calling me bae and things like that I just don’t kno how serious this is at this point we’ve had sex a total of 5 times and 4 of the 5 times he’s finished in me with the knowledge that I have no birth control I’m afraid that I’ll end up pregnant and he’ll bail on me and the kid but I could be wrong idk what to do 😩I’m sooo worried about being pregnant I’m going to wait at least 2 weeks to test tho in all I just want a healthy baby
