I don't have any advice, but I wanted to say hi, cause I'm about to start estradiol/progesterone/testosterone as of tonight. I'm nervous about how it will affect me. The doc thought my thyroid was low, but fortunately the tests came back that it was o.k. Today is the beginning of PB for me.
The only thing that comes to mind is that sometimes eating too little (depending on your workouts) can trigger your body to hold onto weight.
