I Just Recently Went Through IVF Cycle And Had OHSS

I just recently went through IVF cycle and had OHSS about 3 weeks ago. I had fluid in the abdomen but have since lost the weight and returned to normal, somewhat. 3 weeks ago I had leg cramps during the night followed by one major one that left me unable to even touch the floor for about a week. My legs are fine now but I am having dizziness, headaches, shortness of breath, and low body temp of 94.9-95 at times when I don't even feel cold. I don't think it was more than a leg cramp but my husband thinks it may have been a blood clot because I did have swelling in my legs at the time of the cramp. Is this a possibility if I don't have any chest pain?
