Postpartum blood clots

Gaano po katagal magstop yung pagdurugo after giving birth? I'm on my 6th day and anlakas parin ng dugo down there though wala ako tahi. May times din na sobrang sakit ng likod ko. FTM po ako kaya wala idea. Sana may makasagot. Thanks!! #pleasehelp #1stimemom #firstbaby #theasianparentph
