Hello,I've heard that theoretically the pill and antibiotics don't work well together, but they have done studies which show that antibiotics don't actually have any effect on the pill and how well it works. My OBGYN is the one who told me this, I'm not just making it up. And I also have experience with taking augmentin and the pill, and I haven't gotten pregnant. I've taken antibiotics for six months straight, and I have never had a problem. I hope this helps and eases your worries a bit. Have a great day!
