PCOS -- Really really sore breasts??

Hi, I've been on metformin/provera since November. I only needed the provera to jump start my period. After, I was having them as normal until Feburary. I had to take provera and I only spotted (3 days after I stopped it) now for the past week my breast are getting so bad I keep cans of coke on them to numb them. I've been throwing up in my mouth and have a metal taste. Has anyone experienced this with this pill combination? According to bbt and opk I have not ovulated. If my period comes on it's own this month, it would be in two weeks. I don't know how to ease the pain. Tylenol and cold compression isn't working and I cannot wear a bra. Thanks.
