For me, I'd rather go by my last period which I calculated with my cycle length. That gives my due date to be 9th October although the sonographer thinks the due date may be 10th October. it's only a day different but I'll still go by my calculations since I've been tracking my period with an app that's very accurate. Of course, unless my baby doesn't grow as quick as it should be and the due date has to be changed by a few weeks then I may go with that one. xx

My 1st was late, 2nd was late but my 3rd last year was early, so think it will prob be a September baby but cause she couldn't decide what date to put me at I wasn't to sure what to go off xx

Id say 1st but tbh it doesn't really matter baby's rarely come on their due dates and even though it's nice to have a day to look forward to, anytime between 37 and 42 weeks it's okay x
