I'm 52. I got off lightly so far - never had problems with my periods, no pain ever. I've not had perimenopause symptoms except low ferritin. Over the past few years I've had shorter periods lasting 2-3 days plus a few periods which lasted 11 days with very heavy bleeding and low mood (a totally new thing for me). I thought long and hard about getting HRT (oestrogel and utrogestan) for the heart and bone benefits. That's really all I wanted it for. Now I'm ready to take it and have the prescription but for the past 2 months I've been bleeding every day and there is no sign it will stop. So I'm finally ready to start the HRT in the hope that this stops! But I'm about to go away to work for a week followed by a holiday for 9 days and I'm worried that I will have more bleeding or pain etc. Is it best to wait until I return? I am desperate for this holiday as not been away for a year and I'm really tired. A few years ago my doc prescribed Evorel patches and I was in bed for two days with period pain and a terrible headache (never had headaches either). I stopped taking it because I didn't realise that it can take 3-6 months to get used to the HRT. I can't have this when I'm travelling. My plan was to wait til I return and then sit out the winter at home waiting for my body to get used to the HRT. But now I'd really like to just get on the HRT as I'm sick of bleeding every day and don't want that on holiday. I'm guessing my body is not producing enough progesterone to counterbalance the oestrogen and I need the HRT now. What kind of initial side effects can I expect when I start taking HRT?
