Light headed and leg cramps. 36 weeks.

Ta

I am 36 weeks pregnant and yes, I have had leg cramps before. But this morning at around 6am I woke up to use the restroom, and ended up with sharp shooting cramps through BOTH of my legs. Which isn't very normal. I've woken up with them in one leg before but not two. Now they were so bad I ended up waking up my SO. And they lasted for almost 10 minutes. Afterwards I got up to use the bathroom and almost fell over from how dizzy I was. The thing is, is that I knew the dizziness had to have been related to my leg cramps that I had just had. I almost fell over on top of the bassinet in our room and had to use the wall next to the toilet for support. It is now 12pm and I even took a nap and the dizziness has not stopped. Should I call my doctors office? I can't even sit up on my couch the lightheaded and dizziness is so bad.

Update: OB said it is normal, maybe not being as dizzy as I was but being dizzy is somewhat normal. She told me just to rest for the next few days and drink lots of water.
