No last ultrasound?

Ally

Is it anything to worry about if I don’t make it to my last ultrasound at 37 weeks? Like if I have the baby beforehand? I’m dilated a lot and effaced, my OB nurse mentioned there’s a high chance I won’t make it to 37 weeks and a couple days for the ultrasound because of stopping labour early twice and all this, I’m just scared there’s something they won’t be able to see if I don’t make it for that ultrasound or anything but at the same time with my first I only ever had one ultrasound at 20 weeks so
