Im in fourth month now its 17 weeks pregnant, im having lower placenta which was seen in my 13 week scan and hope so it will move upward, can I still feel my baby movements even im having lower placenta, can I travel? Go for walking? And in my 17 week checkup doctor said my water level is less so drink 4 litres of water daily, what should I do to maintain exact water level?? If water lever goes higher in future will it affect baby in womb i.e, the baby would swallow extra water? Please suggest me your answer it ill be helpful for me.
