Omg my 1 boob! :(

So AF is due 2/23, I ovulated on the 8th.. I'm 11dpo and I've had slight cramping but no implantation that I know of, and nausea and headaches with major upper back pains, also creamy cm everyday since 7dpo .. only ONE of my boobs hurt badly especially my right nipple (sorry tmi) but while me and my fiance were taking a shower he went across my nipple and I almost screamed it hurt so bad!! I pushed him back lol I felt so bad... but could it be? Did I concieve? :D I hope so!
