I have a very irregular cycle, period every 2-4 mths. Usually experience mood swings and break out 2 wks prior to me starting; and first 2 days are heavy w/ 3-5 more med to light flow. Okay heres the problem: I just had a period 3 wks ago but 2 days ago (Tues) i started discharging small pieces of what appear to be tissue matter in a very light pale maroon color substance, unlike darkness of period, (amount would be no more than a days usual discharge). I thought I was maybe spotting or starting, and it was just some of the lining. 2ce after using restroom the toilet tissue would appear to have actual bright red blood, again very little. Took preg test..negative, im in no pain, VERY CONCERNED. ANY IDEAS??!?
