At my eight week check up (meant to be six weeks but running late here), my GP told me I couldn't go on the combined pill because I am breastfeeding my baby boy and the hormones would be bad for him and that I couldn't have the IUD either (which I had for most of my twenties) because if it wasn't put in straight after the baby was born it couldn't be put in until I had stopped breastfeeding because it might pierce my uterus as it was put in. I've never heard of either of these things. Everything I can see about the IUD says it can't be put in until 6 weeks (long gone) and I know the combined pill can have an effect on milk but not a huge one? I don't want progestin only pill because that made me utterly miserable last time I was on it.
