Ill Be Seeing My Doc Next Week But I Can't

Ill be seeing my doc next week but I can't wait to knowvmore. At approx 30 weeks I went for an ultrasound at my new doctor s practice. I say approx because previous doctors said it was the most likely but not for sure.this doc said I wasn't 30 weeks back then, that I wss 32. The ultrasound said the placenta was grade 2 and now ive been reading that a grade 2 placenta is too advanced for my stage and im really worried. Some sites say that delivery is recommended if its a grade 2 before 34 weeks. Help? If the new duedate is accurate im 34 weeks now and ill see my doc by 35
