Hi. Tell us more about 'bijuve' - is it swallowed, a patch .........
Sometimes a little extra a few times a week can ease symptoms. However, HRT isn't a cure so can be Trial and Error which can be tiring.
How low is 'too low' - doubling up immediately may throw the body into freefall, so doing it gradually might be the way to go. Hopefully some1 will be along with better advice!
