I usually have really sore boobs in the run up to AF, even more so in Aug when I had a CP. Since the CP, the AF boob pain has almost completely gone. I didn't get it last cycle and wasn't PG and I haven't started with it this cycle. AF due in 5 days and it would definitely usually be quite sore by now. I'm worried it means my progesterone is low since the CP. Can anyone offer any insight? Thanks.
