question: I recently underwent an IVF procedure and my beta was 15. Two days later, it dropped to 12. I was told that the beta should be at least 50 and continuously double. I have been feeling nauseous for the past two weeks (off and on) and I am wondering if this is normal. I was told to come back for another blood test so my beta could be monitored until it reach 5 or less. I was devasted that the cycle was not successful and never went back for another test. Is it common to feel nauseous like this after a failed cycle?
