Had protected sex yesterday next morning sore breasts and cramps . i was not fertile or ovulating according to ovulating calendar either. help !

Hormonal changes: It is possible for women, especially young women to develop breast tenderness and ovarian/uterine cramping due to hormonal changes, despite your menstrual calendar suggesting you are not about to ovulate or menstruate. I recommend treating these symptoms the same - ibuprofen or naproxen, moist heat on pelvis, sports bra or no bra, and limiting caffeine. Take care!
