First Time Went Very Wrong

I started my senior year of high school in late August. I’ve never really gone steady with a guy since I play sports and cheer.
For homecoming the middle of October I invited my brother’s college roommate for my date.
After homecoming we parked at a local hangout used by kids from school doing some light making out.
I had let guys play with my little tits but nothing else so when he ran his hand down my prom dress top I didn’t say anything but for some reason, which I now know why, it quickly got me excited.
When I felt his hand going up my dress I told him I couldn’t do anything because I was a virgin he didn’t stop running his hand in my panties.
It didn’t take long for him to have me totally confused as to what I wanted to do but when he started working my dress up I just raised up so he could then spread my legs for him.
He got his penis out telling me he didn’t have a condom so I pushed him back hesitantly but he promised not to cum in me pulling my panties to the side entering me.
The feeling was amazing so I got in a slow rhythm with him reminding him several times to be sure to pull out before he did anything.
All of a sudden he slowed down so I yelled for him to pull out but he said it was too late at the same time my body reacted to it with an orgasm.
Once he had finished he pulled out putting my panties back apologizing for not stopping in time. Then I could feel it running out of me which caused me lots of concern.
When I got home I realized how much he had done because my panties were a mess.
A couple of weeks later I realized why I had gotten so aroused when we were making out when I missed my period. A pregnancy test confirmed he had gotten me pregnant.
After much consideration I decided to have the baby. I’m 13 weeks along with it due around July 14th,
