Hi, I am 30 years old with one child and recently was trying to fall pregnant again, My periods are on time every month and the only times they have not been was when I showed abnormal cells after a pap smear more then 2 years ago, in which I had lazer on my cervix. 6 months ago I again showed abnormal cells and am now waiting to go back, my concern is I have recieved my periods this month 1 week in advance and for the first day they were extremely heavy with cramping and black in colour. could this be a concern with my cervix again or is it something else?
