Ladies can someone please answer my question ?!

Hey their so this is my 3rd week of postpartum I have birth to a stillborn and I wasn’t bleeding too heavy after my first week.. in my second week I stopped bleeding somewhat.. my lochia was turning dark brown mixed with yellow which I read was normal... then yesterday I woke up bleeding bright red again but I’m worried can this be my period ?? Also I passed two clots the size of a quarter is that normal to still be bleeding ? I am worried I am hemorrhaging please say a prayer for me !

It was hard enough to lose my baby I don’t want my kids to lose their momma.. I have an appointment today.. I’m so scared and worried. Has anyone had bleeding on and off in their postpartum ??
