Paralyzed by fear

I am 7 weeks 3 days going in today to hear the heartbeat and make sure baby is ok. I do not want to go. After my miscarriage last year I am absolutely paralyzed by fear. My father is dying from cancer and we were just given our 72 hour notice on Saturday. If something is wrong with this baby I don’t think I can handle it. I have zero reasons to suspect anything is wrong with the baby but I just do not trust my body anymore. Please helpful comments if you have them.
