Girls, hi! Can you tell me if anyone was put in the maternity ward at 40 weeks due to polyhydramnios waiting for contractions there? How long did they wait? Yesterday my midwife said on Thursday it will be 40 weeks and come to her for a referral if I don't give birth until Thursday. But I don't really understand what they'll do with me there? It's better at home than to rot there...
