... and know that effects birth control. I had sex 3 days after my period and used a condom however he stuck it in a couple of times before he put the condom on. I took a plan b about 48 hours after that. It is now a week before my period and I am having pink spotting I'm my vaginal mucus. I have been checking my mucus a lot the past few days. Could it be a dry cervix, spotting from the plan b and my birth control. Or is it likely implantation bleeding? Please help!
