Thats a good question. You want to learn what estrogen does in your body. Side effects of too much estrogen may be signs of gyno coming on, higher levels of water retention, more moodiness. Signs of low E may also be moodiness, dry skin, low libido, achey joints. Of course the best way to know is to get your labs done. I would wait about 4 wks into the cycle, then get blood drawn. This is the only way to know exactly where you stand. The rest are only guesses
