I have a daughter (unplanned) and had a copper IUD shortly after because I wasn't sure I would want a second baby. I removed the IUD last Christmas and I got pregnant in couple of months but sadly had a miscarriage in April. I've been tracking my LH with ovulation kits and I can't seem to identify my surge for 2 months now. Has anyone had similar issues? I'm wondering if the miscarriage messed up my hormones or if you can be infertile after one?
