Hello! About 2 weeks ago, I developed an abscess on my tonsil and was admitted into the hospital. While there, I was given an IV where I received antibiotics and steroids for 24 hours. After I was discharged I was given a prescription of Augmentin to take for 10 days. During this time, I did have sex for the first time. I am on the pill and I have been for 5 years due to PCOS. We used condoms and didn't have any accidents with the condom breaking. My last menstrual cycle was July 10th. They usually last for a week and begin either on the 3rd day of the white pill or the first day of my next birth control pack. I have yet to have started and I am a little worried (I'm on my second pill of my new pack). I know antibiotics effect birth control, but we made sure to use condoms that had spermicide. Could the antibiotics or even the amount of medication I've been taking (steroids, pain medication, and now antihistamines for an allergic reaction to the Augmentin) affect my period?
