Jeez. I've been on spiro since late November. By Christmas, my nipples were sore. Then I had girl nipples. I've been on a very light dose of estrogen for a week now and I already have breast growth. The thing is, one's bigger than the other. Really, I have one boob. I've heard that happens a lot, though, so I'm not worried.
Lop sided is common in teen cis girls...99% of the time it sorts itself out fairly quickly...
I was going to crack a joke about monoboobs... But, somehow that got me researching the phenomenon, and that in turn led me to women with three breasts... Which is apparently a real thing. The term is called "accessory breast". And my head just exploded. Wonder if that ever effects any MTF folk...
I've never been completely lopsided either way but did notice that the girls would take turns one being just a bit larger than the other for quite awhile, but now they seem to have leveled out fairly evenly
My dosage has been adjusted quite a few times based on blood tests and sometimes I was a bit dismayed as to the reasoning
The Dr. asked if I understood what she meant by 'less is more', what she explained was that slow and steady tended to produce better and more even results over time
Hope that helps
