Do any of you get sore nipples/breasts right before ovulation?? My nipples are so flippin sore

and Im only on CD 18 and I have not had a +OPK yet. They are getting darker but not a + and Ive even bought the digital ones to back up the IC just in case and all - so far. I dont know if the Clomid is making this worse this month but it hurts to put a bra on!
