TTC. Are these symptoms?

My partner and I are TTC and below are the days we BD twice on those days. (My ovulation day was really either the 15th or the 16th) Typically my entire breast tends to get sore and throb when my AF is coming, but I haven't experienced that but I have been experiencing sensitive nipples. What does it mean when your nipples are sensitive to the touch? Like a bra, shirt, or anything I just don't want anything to touch them. Not hurting just very uncomfortable. I've also been experiencing headaches all day.
