Oh I know just how how you feel, Otoko. How did I get by? Well, I was prescribed birth control to regulate my irregular periods
(my periods lasted a total of 3 days - 2 days of spotting/discharge, with one day being a walking crime scene. just imagine 7 days worth in one), so of course I opted for the 3x a year kind. I'm off them now due to medical stuff. They don't really make you gain weight. To me, the relief of only having them thrice a year was worth it. Especially since before mine were so unpredictable. Sometimes it came, sometimes it didn't.
