Am I worrying for no reason?

I am 32+6 weeks today and the past couple days I've been having this "hot flash" kind of feeling only in my right side (from the bottom of my ribs all the way down my right leg to my ankle) and I'm a little nervous about it. I had a doctors/ob appointment on Monday but forgot to mention it my doctor as it had only happened once before my appointment. Any ideas what could be causing this? I have been having Braxton Hicks and they feel different than this and are mostly in my hips/lower abdomen region. Any thoughts and opinions are welcome and would be greatly appreciated.

P.S. I have another appointment on the 6th and will be mentioning it then if not sooner.
