I had a early scan to check how far a long I was due to irregular periods and DP came long - all fine and said I was 6w + 4. (Now 10 + 3) but didn't want to give a due date as it might change at my 12 week scan. DP isn't coming to 12 weeks scan as wants to save his time off / holidays for 20 week scan and when baby arrives. So won't be there when I get my date, so I could add on a few extra days so when we tell MIL he can honestly tell her the wrong date to save me some pestering!
With DD I was due on the 10th but was 13 days over by the time I she arrived and the pestering started 3 weeks before my due date so by the time I gave birth I had a full month of : Any sign of the baby? Are you in labour? Have you lost your plug yet? And other invasive questions from MIL! As well as all the other daily texts / phone calls once I got to my due date from the rest of family and friends asking if the baby's on its way / here yet!
Would be completely unreasonable to add on a week / 10 days to save myself from wanting throttle MIL?
