I had my baby 4 weeks ago. I haven't started back on any contraception yet as my GP told me to wait before taking the pill due to risk of blood clots. Yesterday me and my husband got a bit carried away and ended up having sex, although it was only for a minute or so as I realised it was silly and he didn't finish. How likely is it that i could be pregnant from it? I'm worried now!! When did you start contraception after birth?
