Girls, I'm asking this for the second time now. Since August, my VDM is 25 cm, why? I have an appointment tomorrow, I'll definitely ask about it. But I started to worry myself, my OЖ is rising, but my VDM isn't. Maybe the baby is not lying in the right position? Has anyone experienced this? Please write if you have.
