Estradiol sky high on 300T

Currently on 300mg Test Cyp and 250iu HCG Tuesday Friday. Finishing up week 7 here with my first set of labs and received my Test at >1,500 and estrodial at 203. The only side effect I’ve been experiencing in facial water retention. I do have anastrozole on hand and was thinking of taking .5 of it on the same Tuesday and Friday. Any thoughts on the severity of having estradiol this high?
