birth control, antibiotics, and plan b

I had unprotected sex yesterday. Im on bc pills and 2 antibiotics. I took PlanB after sex. My bc makes me not have periods but sometimes ovulate. I'm a week after my placebos. What are the odds of becoming pregnant?

Hi The antibiotic do reduce the effect of your BC pills, but as you backed them up with Plan B I think you could be err on the safe side.
What you did was right, but to save on the Plan B why not think of condoms.

Good Luck

What birth control other than non-hormonal ones, allow you to sometimes ovulate? What good is that birth control?

I'll be the first one to tell you that it was stupid of me to have unprotected sex haha. I had completely forgot antibiotics can reduce the effectiveness. We always used condoms and bc pills until we got married. That was also the first time is ever used plan b (my stomach is killing me!)

My hormones are kinda wacky due to lots of treatments for endometriosis, adenomyosis, and pelvic adhesion disease. I don't always ovulate, it's actually really rare, but sometimes breakthrough ovulation occurs.

Actually, very few antibiotics affect birth control and the ones that do are usually prescribed for TB.

That being said, birth control along with Plan B definitely reduces your chances of pregnancy quite a bit.
