Bummer with my first pregnancy they gave me a estimated due date of July 8 then changed it after the scan to July 20th but I had him two weeks early on the 8th anyway. My due date with this one ws July 4th then after scan changed to December 31st. They usually date it earlier as later on In your pregnancy baby could measure a little behind or ahead so it's not to accurate then anyway.
And they made you wait till 21 weeks for a scan? They should have done one sooner they usually do one at 12 weeks to find out whether there's more than one. And to check that it's in the right place and not ectopic. then they could have told you for sure.
You might be a week or two shed then. As you might have ovulated sooner how many weeks was you when you found out.
Based it off lmp. But I couldn't be certain on my last known period. Because I was already in my 2nd trimester based off that. I even told her that I wasn't completely sure on that and she said we will just wait till your sono at 21 weeks.
I'm 19 weeks and I can feel like everything she does. It depends on so many things your weight baby may be stronger this time around. How much fluid is round baby. Did they date your pregnancy based off a scan or your lmp.
