37 weeks pregnant

Since I am high risk my doctors appointment is 1 hour and 30 minutes away..... last minute (today) my husband decides he doesn’t want to miss work for a appointment that’s tomorrow and that I would need to reschedule. I had no issue with picking another day.... usually my MIL would bring me but she decided not to ither ..... My FIL is in town and said he will take me ... I’m 37 weeks pregnant and I feel uncomfortable going with My FIL.... what would you guys do?
