I have been to the doctors twice in the past few months and at each visit my blood pressure was high. I am also having heavy/long periods. Could this be the reason for my high blood pressure?

If your periods have just recently got heavier (and maybe further apart?), then this can indicate a lowering of oestrogen which is known to have a constricting effect on blood vessels, possibly then affecting blood pressure.

Also, heavy periods can make you anaemic which could also affect blood pressure as well. However, this could be due to other factors such as stress or anxiety
