20w scan. Questions

Savanah • Thanks for looking at my profile :)
Hello everyone, I had my anatomy scan today. Everything looked good except that he said that placenta is 3cms away from cervix.And the doctor may monitor it in my 28w scan. How much is the chances that I will have a vaginal delivery? Does this in anyway effect the pregnancy or baby? I don't see my doctor until next 2 weeks.
