When I was pg with my son I was diagnosed with placenta previa at approx. 22 weeks. It did "move out of the way" and was completely normal by the end of the pregnancy. There is probably a good chance that yours will correct itself too. GL
I have Aflac and think it's great. I would say $80/ week sounds high but I don't have family coverage and I did not pick all of the options available. I think your rate is also based on how much money you make.
