I just had a baby about three and a half months ago. I breastfed exclusively until the end of December, when I supplimented just a bit, like an ounce, seriously! Then I had my period, a sign that the next one will be "fertile" and that one is usually sterile. Now I am not breastfeeding at all. Um, then I am supposed to start on the 30, I am usually pretty regular even after a baby, but my husband I and I had unprotected sex last night the 25th and I am terrified I might get pregnant! This will be my third surgery (c-section) in three years if I get pregnant. The baby would be born on my baby boy's first birthday or soon after. I had preterm contractions and my doctor warned me against getting pregnant within the next 16 months. What is the likelihood of getting pregnant?
