I’ve been on bc for 3 years and I was prescribed antibiotics on Tuesday July 17 and it was for twice a day for 3 days so my last day was the 19th and that week I was on my placebo week so I got my period Friday and I took the first pill of the new packet on July 22. Yesterday I had unprotected sex with my boyfriend and he pulled out ( I know it’s not a reliable form of birth control) I feel like he pulled out a little late. I just want to know if I’ll be okay or did I not wait long enough since I was on antibiotics.
