I had egg collection on Saturday and am now heading for Blastocyst transfer tomorrow. There were some concerns about ovarian hyperstimulation but that seems ok. I was hit last night with quite bad shivers, shakes, and pains - flu like symptoms. The doctor has put me on paracetamol but I wondered if our chances are reduced with illness. I am tempted (reluctantly) to freeze our blastocyst embryos and go for transfer next month. I just can't believe my body would fall pregnant feeling so ill. Any advice?
