Tinkerbellj, the 19th was only just over a week ago and (presumably) you are now at the tail end of your period so, in my opinion, you still have a fair amount of Utrogestan in your system. Contrary to what it says in the patient information leaflet, Utrogestan stays in your system for a long time and it is not unusual to not feel abnormal until a few days after your period finishes. Re the sweat/flushes, Utrogestan will oppose the Oestrogel and make it less effective so that could explain why you are getting those symptoms.
Looking back at your posts, you say you took Utrogestan for 9 days, what dose was that? It is cumulative and builds up in your system and hangs around in you womb for quite a while when taken vaginally and although it will mainly be confined to the womb, some will leak out into your overall system.
It is vital to find your own threshold with Utrogestan, everyone is so different and it is impossible to know how much you need until your try different doses and then have a scan to make sure it is working properly. One size never has, and never will fit all with Utrogestan and my body says "I don't need any more of this stuff" far sooner than it might for some.
