hCG levels after failed IVF

Becki
I found out last week that our first round of IVF was unsuccessful. When I went in for my blood work, my hGC level was a 4, two days later it was a 3. They wanted me to test one more time to make sure I was at 0 before starting our next round. Results yesterday show an increase to an 8, has anyone else had these unusual results?
