This is what I had - complete anterior placenta previa that never budged. I had my c section last week and it was perfect! My doctor had (gently) warned that there could be excessive bleeding, and I had to sign an agreement for a blood transfusion if necessary, but everything went fine. And even if there had been excessive bleeding, my doctor didn't seem worried about it. It seems routine for the doctors... Many of the scary stories I had read came from women who hadn't been properly diagnosed in advance.
I don't know about you, but the hardest part for me leading up to the birth was worrying that I'd start bleeding early, because the internet had led me to believe I would. Again, my doctor wasn't worried... He said it would start as spotting, I'd be evaluated, and we would deliver earlier if necessary. In the end, I never bled and my c section was done at week 37.
It was a lovely, calm birth experience, my recovery was entirely tolerable, and my baby is perfect.
Don't worry! Let me know if you have questions.
