Hello, all.

I know this is a frequently asked question, but I feel the need to ask again. What are my chances of being pregnant? I'm 16 and a half years old. My period started on January 2nd. On the 13th, I was intimate with my boyfriend, however, it was the first time for both of us. Very briefly (and I'm not exaggerating when I say maybe 1 second), the head of his penis entered my vagina, and it hurt terribly so we stopped. He did not ejaculate, and there was little to no pre-ejaculate. What little there might have been I doubt contained sperm, as he doesn't masturbate due to his family morals. I bled for a day or so afterward due to the penetration. I received a negative clinical pregnancy test, and have not been experiencing any pregnancy symptoms. My period is due tomorrow. How likely is it that I am pregnant?

 

(And to those who are going to tell me to use protection: I understand, and I understand that there is always a chance, no matter how slight it may be. This occurrence was something neither of us anticipated, and we were unprepared. I have already spoken to my doctor and I'm starting on birth control at the end of my next period. Both my boyfriend and I have agreed to not let this incident repeat.)

 

Other items that might have an effect:

- I take antidepressants

- I have recently started a new medication to help control my OCD

- I take an antibiotic for acne

- My periods are not always regular

- I have an anxiety disorder which leads to an extremely stressful lifestyle

 

All things considered, what is the likelihood of being pregnant?

Thank you so much!
