Little confused. 😒🙄🤦🏽‍♀️

So i have u shape funneling and short cervix. Been on bedrest since April. However baby weighed in at 5lb1oz at 30 weeks and Friday i as 33 weeks but i measured 36 weeks. Doctor doesn’t want to change my due date or anything. I honestly feel like he should change my date. I’ve stopped taking my progesterone and I’ve been on my feet more lately just around the house. Has anyone went through this before? (Every ultrasound which was weekly up until 30 weeks baby measured big) dr said “better to let baby stay inside long as possible which is why i don’t wana change your due date) even though everything says I’m further along 🤦🏽‍♀️🤷🏽‍♀️
