Goodness Emo, it's not surprising you had such symptoms if your levels were that high. You might not be estrogen intolerant at all, you might just have been on a very high dose of it. If that was on only 2 pumps, you may not need estrogen yet(!) - it would be extremely unusual for 2 pumps of estrogen to give you that much estrogen, so it would seem that your own ovaries are contributing a lot..... I'd suggest again just trying the progesterone for now. Your symptoms sound like that's what you need...
The Lara Briden book explains all this in detail but basically, when our bodies are functioning how they are supposed to, we ovulate and the progesterone is then produced by the corpus luteum in the last half of the cycle. As we get older, our ovaries often don't ovulate every month and we have anovulatory cycles instead. If we don't ovulate, we don't produce any progesterone. So our cycles can be very short because we don't have the progesterone there to sustain the uterine lining for 2 weeks.
Equally, without the progesterone there, the uterine lining builds up too much and that can lead to a very heavy flow when you do get the bleed.
Do check out the book for more info on using progesterone only during peri. It is very common to do this in the US and there are a lot of US Facebook groups with women using progesterone only - CrispyChick told me about the Estrogen Dominant group, which is very interesting. Anyway - it would not be unusual to use progesterone only, in the US. You would use it in the second part of your cycle, so from day 14 to the end. This link explains how to do that and how to deal with bleeding and timing of taking the utrogestan:
