From reading forums I gather it is standard practice to have a blood test about 14 days after embryo transfer but my scummy FS gave me a HPT to take home. I did that on Thursday and got a BFN but still there is no sign of a period. Is it normal for a period to be late after IVF. I stopped the Crinone and progesterone suppositories on Wednesday. I feel a little bit crampy but not necessarily period crampy.

I was thinking of doing another HPT tomorrow........or should I leave it?
