I find that gap really really big. I dont think that's right. Can you check? I am going private and they're really obsessive about my appt's. The longest gap for me is 4 weeks and Im meant to see my GP (Shared care) in that time. What about your GD test and general measurements, blood pressure etc? THese need to be regular incase of pre eclampsia etc. Doesn't seem right to me. I'd definitely call and see.
Good luck xo
