Appointment went good, 27 weeks today, measuring at 28, baby boys heart rate is 148, and my glucose test is tomorrow morning, did anyone else's ob start seeing them weekly at 27 weeks along?.. My nurse said not to let it bug me but he didn't give me a reason for wanting to see me that much, and she said its probably cause I'm anemic?
