I've always had irregular periods. Six months ago I started to have break thru bleeding about a week or so after my period had ended ( very little blood, last 3-4days) I had sonagram showed to small fibroid tumors, uterial lining measured 6. Other day I had sonagram to recheck. tumors are the same, uterine lining measured 9. Going for d and c. What could these symtoms mean? Cancer? Very nervious
