Currently coming up on my 4th week of 500mg per week, 250mg e3d with 12.5mg asin on pin days. No noticeable symptoms of high estrogen based on what I've read but my nips are constantly hard it seems, mildly sensitive. Been like that for a while and no painful lumps but can't tell if it's the onset and if I should increase asin to EOD. My nips could cut glass. There's not really itchiness but it's weird, almost seems like there's some kind of sensation but it goes away. I just pinned yesterday so I'm not sure if it's the spike. I know bloods are the way to tell but I've been seeing some reports of hard nips. Is that normal?
