Anxious about time between appointments

I was supposed to have my 28 week appointment this morning, but my doctor wasn’t feeling well and it was cancelled an hour before. They asked me if I could come in sometime this week, but I can’t get the time off work. I already took today off.

I am a teacher and taking a day off work is more work than being there. My baby is my number one priority but it’s just hard to take off - especially on such short notice.

I have my 30 week appointment on May 23 - that would make 6 weeks since I’d been last. I feel so guilty. Has anyone else ever had this long between appointments? I’m already anxious about everything baby related so this isnt helping!
