Had to reschedule an appointment because they made a scheduling error and now I won't see my doctor until nearly 20 weeks. Last time I saw them was 11weeks and only for a a urine sample and weight/blood pressure test. Was schedule for Tuesday when I'd be 17 weeks to check on the little one and things and possibly schedule an ultrasound since they didn't at 13-14 weeks because I'd had one done at 9 weeks. Now I'll have to wait another three weeks and with a new doctor no less because mines moving to a new practice and changing hospitals. I just want to make sure my little Kiwi is okay. I've got things that needed to be talked about with this doctor too since I have to fill out a new patient form again so he's not even aware of the complications of my last pregnancy or blood clotting issues. But of course there's absolutely no earlier he can see me.
