I don’t want to get too deep in the weeds here but there are a few things that we have to work around, chief problem being the story’s narrator saying they didn’t know what estrogen would do (it occurs to me it could be a tongue in cheek post by a trans person for lols? “Oh, look, I grew boobs! How’d that happen?” Dunno. Anyway…), then expend the effort to find a way to get them and take the estrogen…because? I mean sure, there’s always someone to find a way around getting something they maybe shouldn’t, but I kinda hit a hard stop when someone says they regularly took pills and they didn’t know what the result would be. Ymmv.
