Could i be pregnant?

I had sex two days after my period ended and the CONDOM BROKE.

Okay so I've been on an off for the past 2 years with my boyfriend who I've dated since I was 15 and I'm now about to turn 21. We were on and off due to distance and cheating on his part that took place 3 Years ago. I moved on and forgave him. Then we separated because things were just rocky and we both were focusing on our degrees. Well now we've been together again the past few months and never had sex until last week. We had protected sex and I have been on birth control but got off due to complications and so I asked him to use a condom. Well this guy gets ultra thin Trojan condoms and right when he's about to nut, it breaks and he pulls out after about 15 minutes. He's freaking out. He says there was precum in the condom. He starts going off on me. He just turns into someone completely different after this point. I understand he's scared so I try to help him calm down and quickly get dressed.

He starts trying to force me to douche and starts telling me hurry up we're going to the clinic. The whole time he's talking to me crazy telling me "You better get an abortion if you're pregnant IDC if you believe its wrong. This was a mistake I will hate you and resent that baby if you are pregnant."

I'm all scared. And confused. 30 minutes later we're at the clinic.

After waiting in the office 30 minutes, The nurse at the clinic gives me the Plan b pill Called Ella. But she tells me that because ive been on antibiotics for strep I had a 2 weeks ago that it may not work.

And I'm just scared y'all. I need advice. If I'm not pregnant I will leave him cause he's crazy and has been hounding me. He didnt even talk to me for the rest of the night in bed he stayed on the phone. Idk if I'm overreacting.

He said he doesn't want a family wit me. Even though he's told me he does. I'm scared of him now he's never acted so crazy.

what if i am pregnant What do i do? I refuse abortion. But can someone give me advice?

Sorry for the long post. I just need some female support please.
