So I took plan b months ago. And recently I went to get on birth control and I told her that. She mentioned plan b could mess up my period schedule for months. I’m suppose to be starting my period any day now. Usually the end of the month. It’s now May 30th, tomorrow is the 31st and the last day of this month. I have the cramps and discharge, but if it doesn’t come tomorrow I’ll be so confused. Can that happen ? Not have your period for a month and then start the next ? I haven’t started my birth control yet because she told me I need to start on the Sunday of my period. I’ve been waiting all month lol. I’m so confused.
