For the longest time I was living with high blood pressure and irregular periods. I started taking blood pressure medication about a month ago and it's lowered my blood pressure to the normal range. As soon as I adjusted to the medication and having a lower blood pressure I started my period. I haven't had any cramps like I would usually get and it's been 6 days and still going strong. Is this something I should be concerned with? Also, is it possible that the drop and stabilization in my blood pressure caused my period to come back? If so could that also be why I don't feel like I'm dying? :)
Sorry you never got a response back in 2008. How are things for you? Any changes or problems with your period. I found on publmed.gov, NCBI, that information on menstrual cycle changes and/or effects on blood pressure "are not well documented, and previous studies have given conflicting results."
From my work experience, honestly, I have not heard or ran into this either. So I am sorry I am not able to give you any further input in regards to this. I hope you are doing better.
