I have these EXTREMELY strong overwhelming feelings. I feel like I am going pass out during some of them. After I have one it takes a little while to remember what is going on around me. They always make me have to go to the bathroom. Then they will subside and I am fine for a while and then it happens again. They usually will last 24 to 36 hours. I have logged them on a calendar and they occur around day 9 or 10 after the first day of my last period. And then they happen again around 7 to 10 days before I start my period again. I do not have them at all during the rest of the month. I have been to 2 different doctors and they have no idea. PLEASE, PLEASE.......I am in need of your help!
