I never had any PMS when I was on BCP, but after my husband had a vasectomy and I went off the pill, I have the worse cramps, and my breasts
sore during/around ovulation time, I have to hold myself when I walk downstairs. I even had to buy a tighter athletic bra to hold the girls in place. I'm not even a large woman...barely a C cup. Any movement at all, even the spray in the shower is uncomfortable at some points in the month.
