Traveling late in pregnancy

Madi
Hi! So my husband and I are the youth pastors at my church, and we had scheduled a youth trip the first week of July. It's out of state, and I will be 35-36 weeks then. We have an appointment next Monday so we will talk to my doctor, but the trip can't be rescheduled because we already paid a non-refundable down-payment. But my question is, did any of you travel out of state late in your pregnancy? And was your doctor okay with it? I really don't want to miss the trip. :/
