What are side effects of Bi-Est?

I have been on BHRT for one month now and last week I started to get a bloated belly and gained five pounds. I called my doctor and it turns out that my hormone medication was compounded to be estrogen dominate because of some of the complaints I had listed. Too much of my BI-est caused the belly bloating and weight gain and possibly repressed the testosterone. They are sending me an estrogen flush and stopped the BI-est. Its trial and error but I'm certain these competent doctors will get me balanced.
