Girls, hello everyone! It's been 40 weeks and I haven't had any contractions yet, they put me on low fluid intake, and my blood pressure is 9.2, and they say that the baby is big, but they're waiting for contractions, is it dangerous for my milk supply to be low? Doctors are waiting until week 41, but I'm scared ? The baby is so long awaited, I'm very afraid something might happen while I wait for week 41, I go for ultrasounds every 10 days, but anxiety doesn't leave ?
