Extremely frustrated after miscarriage

I am 4 weeks and 21 days after my miscarriage and I have yet to start my period. I am so crushed and confused because I just want to start my period or get a surprise that there was more than one in there and that I'm still pregnant. But I have yet to get anything. I miscarried at 4 weeks and 1 day and I figured that would have started my period by now. When my period was due I got some cramping but it wasn't bad and I figured af was coming it hasn't. 😪😪😪😪😭😭😭😭😭👼👶
