Placenta previa at 20 weeks. Who had it clear up on its own?

Ariel

At my 20 week ultrasound I was told I have complete placenta previa. I was put on pelvic rest (as I'm sure most of you were as well). I wasn't really I formed much about it and what pelvic rest really means. Doing g research on my own I saw that alot of cases diagnosed that early cleared up on their own. Is this true? I'm trying not to get my hopes up but wanted info from more momma's in this position. (Currently 23 weeks)
