Placenta Previa?

I’m kinda freaking out about this but at my 16 week check I was told I had Placenta Previa. I don’t know anyone that’s been through it. So please if anyone could give me their stories and enlighten me. My OB basically told me that I would be getting monitored more often and if the placenta hasn’t moved that I most likely get a c-section and I’ll be more likely to go into preterm labor. This is my third baby, My previous births were all natural and fairly quick. So I have a lot to prepare for. Please help !
