For me, it's definitely the bone shedding. I was just minding my business the other day when pieces of my left femur suddenly erupted out of my skin. I rushed to the ER but was told that that was just a normal effect of taking HRT. I was given a pair of crutches, and told to put the pieces of bone under my pillow for the Bone Fairy. I woke up to find $100 under my pillow. Really looking forward to my girlybones growing in!!! 🏳️‍⚧️🏳️‍⚧️🏳️‍⚧️
