It is my first time doing IVF, I am 37 years old, I had one blastocyst 10 days ago transferred. I went today for a blood test, unfortunately, it was negative. I feel devastated, shocked, and angry. I don't know what went wrong. I followed all the instructions regarding the medications, shots, I am just perplex and can't think anymore. By the way, i am 37 years old. Please if everyone had the same experience or heard about it. Please let me know if it is common thing. Thanks a lot.
