Can your length effect your blood pressure?

I have borderline low blood pressure, and have my term right now. I've been have dizzy spells lately, which I have had previously because of low blood pressure. I have also had nausea and headache. Can your period effect your blood pressure? And if not, what could possibly be the grounds of this?
