Girls, 25 weeks, placental previa, itself bleeding, taking magnesium 2 times, did dexamethasone 4 times for it, and the belly pulls periodically, sometimes hardens, but bloody discharge ended, doctors home prescribe bed rest and nothing more is said, the main thing that there was no blood, I'm worried because of the pains they say this from low placenta such pains
