Hi dazned
Sorry to hear you are feeling rough - and especially the headache.
I think we might have discussed this before but I've been away on mini holiday for couple of days and my brain has completely forgotten what everyone's doing!
Is this the first time you are feeling rough on the Femoston conti and are you post-menopausal? Unfortunately some women do react badly to progestogens and also some with oral HRT. Might I suggest you either go onto cyclical HRT so that you only take the progestogen for a short time each cycle or switch to a transdermal HRT which is recommended for those who suffer migraones as having less of this type of side effects?
Are you able to get referred to a menopause clinic? Oh I see you are having an appointment with a gynae - that sounds good - is this a first appointment? If we are able to help with anything specific before then do please ask!
You do need the progestogen to keep the uterus lining thin - and it is unfortunate that many women react to this being taken externally when they were fine with their own (endogenous) progesterone.
Good luck
