Hi Sheila, yes I'm peri-menopausal with a much shorter cycle than the HRT one, usually 25 days. If I alter my tablets to my cycle, would that mean that I wouldn't be taking the Utrogestan tablet for as long as I should be? I'm only on one pump of oestrogen and have only been on HRT for 3 months now and they wanted to start me on a low dose to see how I got on. I didn't have severe symptoms, mainly night sweats and brain fog, both of which have improved with HRT, it's just the dosage and when to take these tablets that's confusing me. I appreciate your help.
