As the title suggests, I got a positive OPK test today at 11am and suddenly at around 8pm i started to get really sore nipples and tender breasts. I couldnt wear a bra and it actually hurts if clothing touches. This is my 2nd month off the pill and i was TTC daughter for 18 months. I've never had this before in all the time i was TTC before. Never even really had sore breasts in pregnancy. Its odd for me!! Has anyone else experienced this? I'm on cd16 now x
