Is Pregnancy Possible In Women Having Low HCG Levels Post IVF Cycle?

Hello, I just finished a IVF Cycle and had my final blood test today to determine if I were pregnant. I had a 4 embryos transferred as day 5 transfer. I did get a positive text, however the HCG level is only 5. That is so low, but is there still a chance that I could move forward to a pregnancy?
