I need some reassurance

Samantha

I had an ultrasound a couple days ago, and my doctor just called and told me that i have complete placenta previa. I’ve never even heard of it until now. I have another ultrasound in 3-4 weeks to check on it. I’m not allowed to lift, have sex or go up stairs. Has anyone had this and it resolved itself before delivery time? I’m 12 weeks tomorrow, so there’s time for it to move, but I’m absolutely freaking out. Any help is appreciated.
