So I'm currently 12 weeks 4 days, due April 9th. At my ob's office I've seen 5 different doctors so far this pregnancy and all but the 5th gave me a due date of April 9th. My MFM doctor also said my due date was April 9th. My last ultrasound gave me a due date of April 9th. I saw the 5th ob on Friday and she said she was going to change my due date to the 12th. I had an early ultrasound during the 5th week for viability so I could start my blood thinner. I have APS. I saw it put me 2 days behind but the first ob I saw said that that wasn't a dating scan and we were going to keep my due date. The second ultrasound put me at April 10th a week later and every ultrasound since then had been April 9th. My MFM doctor said we were keeping it at April 9th but now the ob wants to change it randomly. I'm switching ob offices next week and I'm confused as to what I'm supposed to put down as my due date. Should I keep it as April 9th? That's kinda what I'm leaning towards.
