I'm really starting to hate the doctors I go to. I tried scheduling out 2 appointments in advance because of the holiday season coming up and couldn't because no one in there could tell me how far out to schedule my second appointment. I had to explain to them I'll be 28 weeks at my next appointment and I should be starting to come every other week. She told me no that's not how they work! That it all depends on me and just left it at that.
