Antibiotics And Ovulation
Does antibiotics increase ovulation if you are on birth control? Making it rly easy to get pregnant as soon as u start taking them?
No: There is only one anabiotic that has been shown to possibly decrease the effectiveness of birth control. And that antibiotic is rifampin. This is not a commonly prescribed antibiotic. There is no data linking common antibiotics with decreased birth-control efficacy. ...Read moreSee 1 more doctor answer
Am I pregnant? I had sex 9/2 condom slipped&took an eoc that day.. Was on antibiotics&loestrin24, "ovulating" now 9/10. What are the chances of preg?
Check a test: Emergency contraception is used to reduce the risk of an unplanned pregnancy but it certainly does not guarantee. That being said you were also taking regular birth control of the time. That makes pregnancy unlikely but possible. Check a test to find out. Of note you should not be ovulating if you are taking birth control pills. They work by preventing ovulation. ...Read more

I'm on the pill but was taking an antibiotic. I had sex 3 days before ovulation but partner did not ejaculate. Chances of becoming pregnancy?
Risk is very small: Since oral contraceptive pills prevent pregnancy primarily by preventing ovulation, you probably did not ovulate "3 days after sex". Most antibiotics will not affect pills efficacy or will very rarely interfere with their contraceptive functions as long as you take your pills regularly, without vomiting, diarrhea or other major change in your metabolism. Best ask for a LARC an IUD or an implant. ...Read more

Took antibiotics (amoxicillin) mid-cycle. Im on the pill and was taking it prior and during. Is there a chance i may have ovulated?
Probably not: Most antibiotics don't affect contraception. It's now thought that the only types of antibiotic that interact with hormonal contraception and make it less effective are rifampicin-like antibiotics (treatment for tuberculosis). Amoxicillin is not related. As long as you were taking your BCP every day, you should not ovulate. ...Read more
Haven't missed BC or taken late, started spotting several days ago around were would of ovulated. 3 dif antibiotics b2b last month. Risk of pregnancy?
Low: Your risk of pregnancy is low if you are taking birth control pills correctly. Most common antibiotics don't interfere very much with birth control pills. If you took an exotic antibiotic like Rifampin, it would be a different story. Your risk of pregnancy is low but do a home pregnancy test if you are worried to be sure. Best wishes! ...Read more
