Rosehip, where are you in meno. Is it in Peri or are you post? It doesn't matter really though because when you start any form of hrt this can happen because your body just isn't used to the extra chemicals or trying to up the chemical imbalance depending on where you are at the time! Persevere if you can. You should start to get a picture somewhere by the middle or end of week 2 but hate to tell you that any hrt can take a minimum of 3 months to get rid of the symptoms that were bothering you when you started taking it. Meno Consultants always say 3 months before changing a regime although sometimes they vary doses during that time.
I had to persevere and build up your doses which is the ideal. 1 pump is very low, I am on 3/4 depending where I am in my cycle, but then I had had a really bad time before I got on to the gel. It is the only hrt together with utrogestan which has worked for me but it has taken 6 months on the regime for me to really get any form of life back.
With hrt there is no quick fix 4 days is like the blink of an eye in hrt world - up to you but if you want to know if it works you have to push through the first month at least xxx
