So before my period usually I feel cramps and my boobs hurt so bad until af comes then it stops . But since I started metformin they hurt non stop. So I started in October metformin for my period dec and Jan. I’m waiting for it to come. But this whole month my boobs hurt me so much. And now they feel full and heavy . I have no cramps which is weird cuz I feel completely fine . Also on the side of both my boobs it feels hard . Idk if it’s my hormones or metformin. But it’s kind of scaring me.. I am ttc and my app says af is due Wednesday but I have pcos so u know how that goes...any ideas ladies ?
