Waiting and Nervous

My right leg has been swollen since Thursday. It's becoming painful especially when I walk on it. My left leg swells a lot here and there/now and then as well, but not like my right leg. My right leg has stayed swollen, it's not letting up. I fear there may be a blood clot. I hope I'm wrong. I keep taking hot baths trying to relieve the tension but that keeps making me pass out, fall asleep, or start seeing everything in shades of yellow! I really don't understand the whole yellow-shades thing either because nothing in my bathroom is yellow. The bathroom walls are white and the decor is purple. I'm getting nervous about the possibility of a blood clot because the swelling in my right leg won't let up and it's starting to hurt more and more so I called the Perinatal Center. It's the high-risk pregnancy place. I don't know if I was supposed to call my regular OB office first or not, but I figured I'd call the smart ones first, ha ha. An answering service type of gal took down my complaint about my leg and said she would have a nurse call me back. Thus, I am waiting and nervous.
