Complete Placenta Previa.. Then Nothing!

Strangest thing happened to my SIL this past week. March 8th (she was 16.5 wks pregnant), she had a routine u/s where she learned she had complete placenta previa. Two days later, she says she started brown spotting with clots. It continued sporadically for 5 more days until she let out a "gush" of blood and was admitted to the hospital. They kept her for 4 days before doing an u/s. When they finally got around to it, she no longer had placenta previa (not partial, not complete, nothing). The placenta was right where it should've been and they discharged her the following day. She says she's still spotting.

Basically, it was 12 days from the time she was diagnosed with complete placenta previa to the time of the ultrasound that showed absolutely nothing wrong.

Ever heard of something like this happening?

I know nothing about OB except the extension to call when we have an OB pt we need help with. LOL. But I wish your SIL the best. Keep us updated.

Transabdominal U/Ss for previa determination don't carry as great an accuracy as do transvaginal U/Ss (98-99% accurate). It's possible she was misdiagnosed, either due to an inexperienced tech or not-so-great equipment which threw a shadow on the monitor.

However, miracles do happen. I had my own previa issue 6 months ago. Two different techs determined a complete, one of them via transvaginal U/S. Six weeks later at 24 wks, it had moved 4.5 cms -- which just doesn't happen in that short a time frame.
