... next day because all I had left were green pills. I figured I would be ok because it was just 1 pill and it was my period week .I bled wednesday-Monday and then I had unprotected sex today Tuesday and I will not start my new pack until thursday night. Pharmacists says I should not take a plan b bill because too many hormones. Should I be worried? Or should I just start my new pack Thursday like always. Iv been on aviane for almost a year now
