38 weeks and 4 days, no appointments?

So I haven’t seen the doctor since 37 weeks. They said they have no appointments available, but I’m supposed to go weekly... I hope my doctor don’t think I’m not coming? I’ve called the receptionist cause long story short they only had one opening for me to choose from & I couldn’t make it. My doctor is over and hour away and I can only go between 11am-1pm & the only appointment they had was at 4:40pm. That’s what I’ve been doing my whole pregnancy, no problem. Now they have no more openings when I’m at the end of my pregnancy.... I currently have no appointments in the future & im honestly frustrated... like isn’t this important? I’m due July 29th. Idk what to do? Just wait till I go into labor? This is my first pregnancy...
