I had sex 5 days after my period started and I'm on birth control. I was also on an antibiotic. I took plan b the day after the sex. A week later I had extremely light pink bleeding followed by very light brown. Implantation or normal for plan b?
Next time, use a condom as back up. If antibiotic decrease the effectiveness of the Pill, they will decrease the effectiveness of Plan b as well. One thing for Plan b is that it is a very large blast of hormones. Next time you take antibiotics, either abstain or use a condom with spermicidal foam or jelly to be sure that you have a reliable back up
