Hi. I have been having a weired expirience in my menstrual cycle
First of all I had pre cancer cells and did a cryp therapy thing where they freeze the cells and ever since after that my period has been weired.... i will have all the signs and symptoms of period but no full on blood...i will be spotting light brown a week before and then on the day of period it only comes out when i pee. Dark red and thick sometimes i use a pad (it barly fills it) sometimes nothing at all...i will have maybe 2 days of bleedinf then it goes away for a day and comes back....also before all this my period would last 5 6 days first 3 beeing super heavy. Also a week before my period if i have intercourse i bleed alot during sex ALOT!! Bright red. And then it just stops and goes away and becomes light spotting...i have all the symptoms i usually get. Fatigues break outs bloated moody but. No blood...I am Some sort of an athlete and work out alot ans lately lifting heavier then usual could this cause all that??!also last papsmeer 8montjs ago came all good!! I am extremly stressed and its affecting my sex life....
