I'm very in tune with my body, and notice changes quickly. The last two weeks I have had indigestion almost daily, I'm tired, my nipples and breast and tender I slightly run my finger across my nipple and I definitely feel lots and lots of sensation and she perks right up pushing causes slight pain. I feel bloated. Took a HPT and it was a big fat NO! I have pcos I've known for the last 12years. Been off metformin and my vitamins for a month now but going back on them. They definitely do help. But any ladies know what could be causing my nipples to be hyper sensitive?
