Possibilty of getting pregnant durin the six weeks after giving birth?

Okay so i just had a baby 2 weeks ago today by C-Section. I did an adoption cause im only 15 i wanted to get my life started (finish school college get a good job etc.) so im not breast feeding. Last night me and my boyfriend were cuddling (same guy who previously got me pregnant) and hes like a sex fanatic sometimes it seems like its all he cares about. We didnt have intercourse but he pulled my pants down and had his penis between my legs; my underwear was on so i didnt think anything of it. He rubbed his pre ejaculation on my thighs around my underwear and later fingered me he switched hands. i dont know if he had pre ejaculation on his fingers. I wouldnt have let him finger me but i know from past experiences that if i tell him to stop or fight him he only gets more turned on and will hold me down because he has a problem with blacking out and having no clue what hes doing and he wont remember. So i layed there and let him. Once again there was no intercourse just fingering. But after words i went to the bathroom and washed myself down there with soap and water. Today ive completely stopped bleeding too... Is there a chance i couldve gotten pregnant again? And how high is the chance? Im absolutely terrified right now i made a huge mistake i know i have so much regret on myself right now i cant be pregnant again i have so many goals for my life and i need to catch up on school im far enough behind from having my first baby. And if i have a baby again ill have no choice but to abort it. My plan was to finish school go to college to become an OB nurse. Get a job. Get my life on a track live a little then at about 27 have another baby. I dont want to put this dream/ goal on hold again. Please any help and please im begging no negative comments i know i messed up again.
