I'm scheduled for this on the 26th. The lady who I scheduled it with told me to do my finger pricks after nine weeks but not more than 10 days before my appt. the lady at my doctors office said it didn't matter as long as I was past 9 weeks. She suggested I do it today .... But obviously there are more than 10 days until my appointment. I don't want to do it too early. Wwyd?
