Laetitia, I can sympathise. My hindwaters went at 36 weeks, and then I went 2 weeks overdue. I had 6 weeks of people ringing to see if I had had the baby yet. I wanted to throttle them by the end, and got my OH to answer the phone. Calls would go like this;
Have you had her yet?
Ooops - did I forget to tell you, had her days ago!
Are you in labour yet?
Yes, hang on, just having a contraction!
Are you feeling anything yet?
Yes - a desparate desire to punch the next person who asks me when I'm going to have the baby!
I would be polite but firm when people ring, and say that you appreciate them calling, but that you are feeling a bit tired to talk at the mo. If they want to they can give their best number so that when baby is born OH can send a text or email as soon as possible so that they will know straight away. But in the meantime could they refrain from asking as it wears you out answering the same question 3000000000000 times a day!
