I have been on reclipsen for 2 months and I am currently on the first week of month 3. I only took the antibiotic Amoxicillin for 1 day on thursday 3 times that day. The next day on friday I had unprotected sex with my boyfriend. We both were kind of panicky so I called my doctors and pharmacists to see if I would be fine. They said I should be good because I have always taken my pill on time and never missed a pill but there was still some chance. So to be sure we got plan b and I took it within the 12 hour mark of having the unprotected sex. I still continued taking my birth control at the same time. Now my real worry, I know this may sound stupid, but the day after I took the plan b on saturday I had unprotected sex again. Am I at risk of becoming pregnant? And is the antibiotics out of my system? If not how long does it take to get out if I only took the antibiotics for one day? Thank you for anyone that has an answer for me.
