Hi I had a 10 pound and 11 ounce baby and the doctors were worried about my bleeding. Now it has been five months later and I have started my period but it has been going on for a month in a half I have only been with one man since my baby was born but it seems the bleeding started after I was with him and now I am starting to cramp a little but I know for sure I would not be pregnant cause I used the depo and took myself off of it in June so I would like to know if bleeding and cramping can be a sign of any STD. Please help me I have no medical insurance and cant pay large medical bills.
