I really need help please

la

I’m really afraid because my doctors office isn’t even open for me to call. But I’m 7 weeks postpartum. I stopped with lochia (post partim bleeding) around the third week. But yesterday ( at 7 weeks) I started bleeding again. I’m talking about saturated pad bleeding and every time I get up I feel it come down. Has anyone had this before? Im worried because I’m reading that I may have to get my uterus removed if this is serious

Also, I am not feeling any cramps so I don’t know if this is my menstrual cycle
