Marginal Placenta Previa

LJ • Baby girl born Feb 19, 2015 and second girl born Jan 20, 2017. Baby #3 due in October!
I just had an ultrasound at 23 weeks + 5 days and the tech said I have marginal placenta previa. We will do another ultrasound in a month but for now the only restriction I have is no intercourse, just at the time I started to enjoy it. Who else was diagnosed with it about this time frame and did it resolve itself?
