Feeling like a failure

I originally planned to work until my due date. I’m a doctor in a resource poor area. I know how much my services are needed. Then I hit 32 weeks and a basically hit a wall. A full day of clinic was causing 8 hours of Braxton Hicks after and I was exhausted. I planned to come back 1/2 time after the holidays. Well after my first 1/2 day of clinic at 35 weeks I had 18hrs of Braxton Hicks that didn’t stop no matter how much water I drank or tried to rest. So last Friday was my last day and we are trying to make it to term.
I know my health and my little ones health comes first, but I know the havoc it will wreak having to reschedule all of my patients and how frustrated they will be. I’ve already heard about how upset they are that they keep getting rescheduled and how I’m never in the office. I just feel like I’m failing even though it’s the right thing to do.
