Taking 100mg of Utro for 15 days in a row, you really should be getting a withdrawal bleed each month. Perhaps cos you went through meno so early, you have very little oestrogen circulating in your body, and there is not much lining to build up. Are you symptom free on the 2 pumps per day, you could up it to 3 and see if you get a withdrawal bleed on this. First prize, of course, would be, to have a scan, in order to see how the lining of your uterus looks, this would then give you a very good idea as to why you are not bleeding when you stop the Utro as technically you should be, I can only think that you are not taking in enough oestrogen, to build up the lining, perhaps have a chat to your Dr and see what he/she suggests. The gel plus Utro is a lovely combination and most ladies, do very well on it, so maybe your body just needs time to adapt, I would give it a few months and see if you still dont get a bleed, then you may have to adjust your dosage.. you may still get a bleed, mine comes about 4 to 5 days after I have stopped the Utro.. I would also use it vaginally and perhaps use 2 pumps of gel at night, why are you splitting the dose, it is not necessary, you could use 2 pumps and night and one in the morning if you feel that you need more oestrogen. All the best.
