39 Weeks Pregnant - Traveling for Funeral?

My aunt/second mom passed away this morning. They are planning on holding a family-only graveside funeral in two days which is in another state - approximately a 5 hour drive. They are also planning a memorial service for everyone in 2-4 weeks.

If you were me (39 weeks pregnant) what would you do? They are asking if I can come to the graveside service but don't think I should be traveling this late in the game?

Any advice on what you would do/say to the family would be greatly appreciated.

Thanks in advance <3
