Chest tenderness

Bloating ws  the first sign for me i started tracking symptoms daily and it helped me catch estrogen spikes before they became serious

Bloating and water retention

First things to watch are water retention ,puffy or sensitive nipples, mood swings, and sudden bloating those usually show estrogen creeping up best move is to keep an eye on bloodwork and have an AI ready if it gets out of hand but don’t kill estrogen completely. You still need some for joints, libido and overall balance
