Hi. I am two days post frozen embryo transfer . One day after transfer I felt achy and had a low grade fever of 99.3. Today (two days past transfer) I have had diarrhea , aches, and chills. Fever is still around 99.3 - 99.8. Should I be concerned? I did notify my nurse, who said that I should only see someone if my fever reaches 100.4. No vaginal discharge , no vomiting. I had an HCG injection immediately after the FET and am currently on Estrace and progesterone .
