Hi pinkmarshmallow - your post seems to have appeared three times - hopefully you can delete the others or at least delete what you've said! I can't make out the sentence at the end but guess you're asking for advice. It depends where you are in menopause, what your periods were doing before you started HRT, and how old you are. If bleeding is unpredictable, this could be due to your cycle or sometimes random shedding of the lining if it has built up - though your oestrogen dose is not high. If you don't want a Mirena coil then one way is either to increase the amount of progesterone ( eg 300 mg) which I think is recommended by the British Menopause Society in their paper on progestogens (sorry no time to look now) OR increase the duration - so taking the progesterone for say 21 days instead of 14. Sorry can't help with the migraines but sympathise. Have you identified when they occur in your HRT cycle or if there is any pattern? I get a lot of vivid dreams when I am on the Utrogestan phase of my cycle.
