Need advice...

So when I first went to my doctor appointment for this pregnancy I accidentally gave him my last cycle date of 3/17/2019. However I realized about 3 months ago that was inaccurate and it was actually on 3/3/2019 and I missed my cycle in beginning of April and had positive test on the 14th.

Now when I told him the mistake he pushed my due date back instead of ahead from 12/22/2019 to 12/27/2019... that confused me since I told him my cycle was actually earlier back than I thought.

Now my question is,

Could he be wrong about my due date? He says I’m measuring for the 27th with my fundal height but when I had ultrasounds she’s always measuring ahead. I have a gut feeling too that she’ll be here around the 13th..

I had an appointment yesterday and he refused to check me even though I’ve been having lots of pain and pressure too. So I haven’t even began the dilation checks.

Any thoughts mamas? 🥺😳
