My girlfriend has had a miscarriage and an abortion within the last year. There is a history of endometriosis in her family (grandma/mom/etc.). She stopped taking the pill oct. 31 -when her period started, she then had another period nov. 31. We had sex dec. 20th and she did not get her period that month. She has taken a store-bought pregnancy test that showed positive. What is the likelihood of her being pregnant and having the baby? Please help!
