My period is not due until the end of the month. Since the mid of ovulation days my breast have been hurting like never before. I though when my ovulation days were over the pain was going to go away, but no, my breast got very swollen and I can't even sleep right. Putting or taking the bra off is horrible. I already have 3 kids and these never happen before. How can I get rid of this pain? I don't have insurance to se a doctor. Is this a really bad PMS!? It's been 8 days already and my af is not to be here until May 30th. I'm never early on my period, I'm usually 1-4 days late.
