Pregnancy Risk After Unprotected Sex: Factors & Chances

Question
hi I had sex for the first tme on New Years Day. I am on birth control but am
also taking antibiotics, we didnt use a condom but he pulled out.  I was on day 6
of my cycle.  what are the odds that I'm pregnant.

Answer
Dear Laura,

Day 6 would not be the most fertile time of your cycle. And, although antibiotics definitely can decrease the effectiveness of birth control, you are on it nonetheless.

Just for your own future knowledge, "pulling out", in and of itself, is not an effective method for birth control because the pre-ejaculate that seeps out before actual ejaculation actually has a very high concentration of sperm cells.

However, all things combined, while pregnancy would not be completely impossible, I would say your risk is low.

I hope this information has helped you and answered your question! Please write again with any additional questions.
