This is my first treatment cycle ( ovulation induction ) and I was on progestrogen and estrogen support for 14 days . Since the ovulation I had breast tenderness and pain when I touch it .i stopped my progestrone and estrogen only two days ago but i got my periods .today is my first day of my periods and still I have breast pain when I touch. What would be the reason for this ?is it normal ? Which harmone is responsible for breast pain I use to have breast pain in my natural cycles after ovulation and it will go away  before one or two days of my periods but this treatment cycle is different .
