They are very low doses.
I take 2mg Femoston conti, and I’ve had no trouble with libido at all.
Saying that, if you’ve just increased, it might take a while to filter through, as it were.
See how you go on the increase, because taking too much HRT can be as bad as nit taking enough.
Keep us informed, and maybe someone else can offer advice.
Good luck. Xx
