D/C and spottin

I just had a frozen embryo transfer on Wednesday 5/27/09. They transfered 2 embryos which were day 5 blasts. Yesterday I was feeling a little crampy but today I have alot of cramps, pain in the lower left side, spotting and some discharge that is a little thicker than egg whites. I am also nauseated. This to me feels like I am going to be getting a period. I dont want to call them and sound like an idiot if this is just normal. Has anyone else experienced this? Thanks for any help or support, I am freaking a little :(

Opps I spelled Spotting wrong sorry. Forgot to mention that I am doing the Crinone inserts once a day.
