Was assaulted, need advise!

Happened Friday night, Was non consensual I’m afraid of my pregnancy risk.

I met with a friend with benefit who I thought I could trust, we mainly just indulge in oral sex as I am a virgin.

Last night he kept putting his dick inside me even after I repeatedly told him not to. He’d stop and try again after some time. From what I remember he was (barely) inside me for 1-2 minutes around 3-4 times. But he did not finish inside me but on my legs an hour later.

I’m worried about pre cum? Or I don’t know. I also use Diane 35 as birth control prescribed for PCOS and have taken a pill every day (not at the same time)

It’s a 21 day pack and tomorrow is the last pill. Do I not take a break?

Please please let me know if I should be worried about pregnancy
