Brest pain and heaviness with tiredness

hi,
I have a cycle of 28 days. I get a mild lower abdominal pain during my ovulation which will for 4-5 hrs usually. This month I think I was ovulating on 14 or 15 April . I have been experiencing discomfort in my breast since then. Initially it was accompanied with tiredness and lower abdominal pain. After 3 days it's discomfort in the form of pain and heaviness in breast.
Please let me what am experiencing or is it normal.
PS: I am married and had intercourse in this cycle.it's just 18th day of my cycle.
