When I was 17 weeks I went into the ER because I was in so much pain I couldn't walk. They drew blood, a urine sample and they did an ultra sound and found I have a very very early UTI and my ultra sound showed I have a very low lying placenta that needs monitoring. My next scan is at 23 weeks. I was on bed rest for a week and yesterday was the 1st day I had 0 pain. I was not informed anything about placenta previa. I googled info but ya get the worst stories. Does it correct itself with growth eventually?
