hello I am MtoF and have been on spiro and estrodial for about 3 years. This past year I have had trouble with my heart rate going high in a short amount of time with any basic activity. Like walking my heart rate would go up 120+ in seconds. Sometimes my legs would burn going up the stairs to the 2nd floor of the house. I basically have no cardio.Any kind of exercise it feels like my heart can't keep up and I am not getting enough oxygen. I am fit and 125lbs at 5'7 and used to be able to jog 2 miles but I can barely walk now without my heart going out of control.
I have not changed gender marker on ID yet so when I get my blood work done the counts come back as low but I am told they are normal in the female range.
I have had 3 ecg, 24 hour Holter, 2 xrays, and everything they say looks normal.
One doctor says nothing is wrong but another one says that I have low blood volume causing my heart to work extra hard and he thinks it is the HRT.
So I am not sure what else to check because I sure as hell don't want to stop my HRT but this is a problem.
I need to go for my surgeries this year like FFS and a Orchi so I want to be well.
Here is some blood work from last week. I have it done every 3 months and they have come back with consistent numbers.

Thanks
