Am currently trying to conceive and am ovulating today. Over the past 24 hours, my left breast has been very sensitive and sore, to the point that I have been taking tylenol to manage pain today. My nipples are usually sensitive and sore during ovulation, but this is much more painful than usual, and only the one breast aches. I have three children, all whol breastfed for 12 months+, but the youngest is almost three and stopped nursing at 14 months. Almost feels like my breast did when I had a previous yeast infection in my breast while nursing my now 4.5 year old. Or like when my breasts would get engorged. Is this normal or should I contact my OBGYN?
