IVF question

Pros and cons on testing out the trigger shot after transfer?! I didn’t last time until two days before my bloodwork, and only then because it was my hubby’s birthday and I wanted to surprise him, it was negative and I went in for bloodwork and they said I was having a miscarriage so because of the test I was able to somewhat prepare myself however it was still obviously heartbreaking...we are in our second round now transfer will be next week and I just need help with a pros and cons list because I keep going back and forth on testing out or not! Thank you in advance!
