No clue how far along i am

Morgan

Had a miscarriage sept 17th, 6/7 weeks along. I stopped bleeding September 26th. My hcg was 11 on the day I stopped bleeding. By sept 30th it was zero. November 3rd i finally was done waiting for my cycle return so i could get my birthcontrol put in, and i get a positive test! I have a pretty regular sex life with my husband, and we dont really use condoms but instead use spermicide gels, a diaphragm, pull out method all combined so i cant track conception that way either. im also supposed to be infertile(according to docs before we married), but here we are pregnancy number 4 (2 miscarriages, one live birth). Anyone have idea what range of weeks i could be?
