Interesting -- when I had blood-loss anemia after Peter was born (lost around half my blood supply, you may recall), my pulse rate went through the roof, but my blood pressure didn't change that I recall. But I tend to have low BP anyway.

I should be reading more about perimenopause myself, but unfortunately everything seems to be about the more common symptoms with just a vague sentence or two saying that some women get the opposite, and I seem to be getting lots of the opposites. Very confusing. It's like when I was pregnant and every single book I read said that I should be producing tons of cervical mucus due to high estrogen levels, and that it would be the opposite during breastfeeding. Surprise: I do it backwards (though not in high heels ...). No problem producing either babies or milk, so it's apparently all normal.
