Hi I am 22 yrs old and pregnant with first baby.I had a scan at 21 weeks. All my reports are normal. Except one it says placenta posterior stops 2.0 cms above the osmosis, grade 1 maturity . What do I understand by this? My doctor said we will again scan after 6 weeks and will go up? I am having two questions. I want to have a normal delivery. Is this going to lead me to c-section. Do I need to take rest not climb staircase, not sit folding my legs, not stand long, avoid relation with my husband. I would also want to ask if I could travel by car for a distance which may take 2-3 hours journey. Pls guide me
