Quoting MissyMom0812:" Exactly. A due date can be wrong 2 weeks either way. So if you wait until 42 weeks, you could really be 44 weeks. I don't know it's just not some thing I would risk."
And there's that! With my daughter, they completely calculated wrong, and I, for some stupid reason, didn't figure it out until well afterwards! They calculated my cycle off of a normal 28 day cycle, and I was going months without a period. With this one, I know when my last period was, I tested with a BFP the day my period was due, and was late, and had an early US and all that. I'm fairly confident my EDD is accurate (in the sense...) this time around.
I know I still have time to go into labor naturally, but I'm starting to reach that point of feeling like since it hasn't happened yet, it just won't happen at all!
