Yesterday i had normal cramps and loss of appeite (thinking okay this must be my period) i used the restroom and a white sac-like thing came out about two or three inches long. I wiped across it with tissue and a piece broke off. It had blood in the inside. I know it wasnt a condom because it wouldnt have broken apart. Now im bleeding light.... not usual for my period. I dont think i could have been pregnant but i was 10 days late as of yesterday because i just started a new birth control pill. Can someone tell me what this is.?? My nurse is out of the office till Monday, HELP!
