Hi, I had my copper coil removed 3 weeks ago, am now on cd34. Normal cycle is 29 days. I have sore boobs, so feel that AF could be coming, but they've been sore a week now. Been testing frantically with FRER as well as cheapies but lots of BFN. I'm beginning to worry that something is wrong, but telling myself that it's my body adjusting to the coil removal. This is normal, right?
