I cut up both the evorel 50 and the conti into half, as advised. I was having regularish periods before I started even though I am 57. Since being on HRT I have had periods but they do vary in timing and duration, not as heavy as they were. After a few months they settled down to being the third week of the cycle for a few days. Having increased the dose they are more erratic, but I'm guessing that this may be because its early days on a whole patch. I waited for several months before starting HRT after getting the prescription and built up very slowly. In retrospect I wish I'd taken the plunge earlier. Good luck.
