Can someone please help me out, myself and my husband are TTC. My ovulation was on the 11 of November, and we bd, about 3 days later my breasts were very sore and sensitive (they still are), on the 21st I started very light spotting, which stopped by that night, then on the night of the 22nd it started again, and now it looks like af has started, but it's 4 days early. Still have very sore breasts and nipples, back pain, cramps, and nauseous all day? Any advice on what could be happening?
