sometimes ill have my period or random bleeding n it will sometimes last for a few weeks... im getting confused because the doctors tell me its nothing serious that it normal but I honestly have never met nyone who has random bleedin for long periods... this last time I started bleeding a week before my due period then my bleedin lasted for 2 more weeks after that so I ended up bleeding for at least 3 weeks... soo.. ive been trying to get pregnant for the last 6 months n its not happening, could this random bleeding b a cause of non-pregnancy??
