Dp has realised he's going to be abroad when I'm about 36 weeks pregnant, for a week. I said not to worry, I'll be at least a week over, but now I'm worrying. I think I have been overdue both times (more than 10 days over) because both were back to back and so not putting pressure in the right place iyswim. So if this one decides to go back to back I'll assume I'll be late, but if it behaves and puts itself in a good position, am I just as likely to go overdue? I've realised that I am completely taking it for granted that I'll be overdue, when it might not be the case at all
