Negative HPT 8dp5dt

I am really bummed. This is our first round of IVF. We do have 3 more frozen embryos which is great. I just really wanted this to work. We have been trying for 5 years. I have had 3 CP, 1 partial molar twin pregnancy, and an ectopic where I lost a tube. If this doesn’t work that makes 7 angel babies. Our infertility is unexplained. Everything checks out normal I just haven’t been able to carry. Should I still hold out any hope? My first beta is scheduled for Wednesday morning. If it doesn’t work should I ask for any more tests before a FET? I feel so sad and defeated.
