It's not very common, but you're right, my usage of words was improper
I wouldn't say u don't deliver on time. My first was exactly 40 weeks to the day. @watson0722
Take an clear blue pregnancy test with time estimator on it. It's digital so It will tell you how far along you are
Once they get the first ultrasound you will know best. Besides that there isn't a great way to tell unless you know the day you conceived.
Days can be converted to weeks....:)
Take 280 and subtract # of days between you last period and today. This should give a good estimate how many days you're along
Thank you, I guess I'm more curious about how far along I am than the due date. Nine days feels like a prett large difference in the first trimester.
You never deliver on time, so don't worry, just have a safe pregnancy :)
