[|Human|] Doctor, I just started my new cycle of birth control medicine. I have taken every pill correctly for almost ten days now. My boyfriend and I had unprotected sex the night before I was about to take the seventh pill to stop my ovulation. he did not ejaculate inside me, or at all throughout the whole encounter, but he did pull out because he thought he was about to. What are my chances of being pregnant?
[|AI|]  Hello, Welcome to Chat Doctor. You are currently started birth control pill (more than 99% protection is achieved after 1-month used) and did unprotected sex with pulled out method, which has HIGH failure rate (15-27%). It was quite risky sexual intercourse. In this case, you have LOW to MINIMUM chance of pregnancy as it was close to your fertile days. You should continue those pill regularly on scheduled time. Do home pregnancy test if you miss next period. Practice safe sex in the future. Good luck.
