I didn't have a clue, all I know is I was complete dreading labour!
My waters broke in the night when I got up for a wee, I was exactly 40 weeks. I suddenly felt so calm and relaxed about it, my labour was 2 days but I felt totally at ease and in control, completely different to how I imagined!
This time, I have a feeling my little boy will be early, I didn't really know when I conceived but when I went for my dating scan I estimated myself at 14 weeks, I measured 11 weeks, since 20 weeks all my scans have measured 3 weeks ahead, therefore I think I may have been right all along. I'm 34 weeks measuring 37 weeks. So I think he will arrive in the next 3 weeks!
