I started HRT 2 weeks ago - 2 pumps of oestrogel every day, then 2 100mg tablets of utrogestan for 2 weeks. This morning I started my period, even though I have only used the oestrogel so far (I'm on day 14). It's quite heavy with bad stomach cramps, definitely not spotting. It's 30 days since my last period ended. So would this be my own hormones breaking through? My periods were still pretty regular (though the last one was a week late and lasted for 3 weeks). I didn't start the oestrogel at the same time I started my period. Should I have waited? I can't find anything about this on the internet, and the clinic haven't got back to me yet. I'm not sure whether I should take the utrogestan tonight? Stop altogether and start again when I get my next period? Or do I need investigations?! Anyone else had this. I'm 48 and symptoms have been low mood, irritability, low energy etc. No hot flushes or physical symptoms yet. Thanks
