Help!! I'm concerned

I've been on the pill just over 6 months and a couple of days ago I just started my new pill packet.
I started working out again at the same time of starting the pill packet and today I stood up, my legs went completely purple and patchy and were on the way to pins and needles. 
I looked this up (I know.. Self diagnosing) and it had a lot of stuff about low blood pressure. I know that the pill can affect your blood pressure, should I be worried? Or am I just being too cautious?
