Originally they thought the previa was just marginal or maybe partial (meaning close to/on the edge of the cervix or just partially covering it, and these are the previas that account for that 90-95% that migrate). But, a vaginal u/s noted that it was indeed complete (which can be REALLY bad).
My thought yesterday, when I was discussing the results with the midwife who consulted with me after the U/S, was that if you couldn't even originally tell, well that's a good thing, right? Because it must mean that the placenta is closer to a marginal/partial previa, and isn't clearly and over-apparently smothering the cervix. More like just hanging out closer to the edge (which gives a much greater percentage of shifting off the cervix as the uterus grows).
All she kept saying was, "a complete previa is a complete previa, we don't differentiate" which, No freakin' Duh, I get, but give me some kind of hope here. I don't know, I'm just freaky and sad, and scared because I realize how utterly dangerous the condition can be if you fall into that 5 %. My homebirth midwife said she'll consult with the OB/GYN practice that performed the ultrasound and get a better idea of what is going on.
Mostly, the idea of going back to a hospital makes me cry on cue. My fear of not only having a c-section, but mostly losing total control of the process after, has my doubled in knots. I know they'll take the baby from me. Tell me I can't hold her. Put her under the lights to warm her. Everything that I deem right & needed will be thrown out the window for the good of the institution. I just don't know how to navigate all the fear I'm feeling. I realize I have to stop being hyperbolic about it and keep it positive, but 2 months seems so long to hang in the unknown, just hoping it shifts before the next check in. Waaaaah! I'm real scared.
On an aside, my beautiful GIRL is complete and perfect and we now have one of each. We couldn't be more blessed.
