sorry if I confused you...up the gel now to 3 pumps and you will just go along until you need to start your utrogestan. Start the Utrogestan for 12 days as is prescribed for a cycle. depending on the day you stopped the continuous utorgestan, count 15 days on gel only and start the utrogestan again for 12 days. I wouldn't push it to 4 weeks with gel only right now, you need to get into a proper cycle. I cannot say if you will bleed for the holiday...no one would be able to predict, your body is going to do what it is going to do.. Take stuff with you just in case.
I cant say about the headache either...I suffered for years and was given sinus treatment, antibiotics, mirgraine medication but nothing fixed it until I got my hrt right. If you have not had them before then I would suggest oestrogen levels but until you try upping your oestrogen its very difficult to tell.
At the end of the day...you might have to change the type of hrt but don't even think about that now...you need to rule out what happens and doesn't happen on the one you have got before you could even contemplate changing xx
