I've been having strange periods for over a year now, smears, swabs for sti's, ultra sounds, all clear, i decided to ignore and maybe it would regulate it self, which it did for a while but now the periods are back, heavy, frequent. I can have up to 3 periods in a single month, some lasting 4days others 2days and this one over a week so far. I also have other symptoms such as head aches during a "period", dull aches all month, irritable, mood swings can be really bad, im due to go back to the doctor soon but seeing as they keep saying im fine, i am exploring and doing my own research to rake with me to try get it all investigated more thorough. Has anyone had anything like this happen to them?
