Hi Heather, Yes my POTS symptoms are more severe during my period. I'm figuring it's the hormone changes that affect the ANS, and just the loss of blood. It takes me a week (two this month) to get back on the up-swing. I do not know any tricks to improve this so if you find ANYTHING out, please keep us posted. I have an appointment next week and this is one of the things I am going to address.
