Miscarriage/possible rainbow baby

So last year I found out I was expecting my first and then my world came down crashing me. I miscarried In November and now I’m 3 days late I don’t have any symptoms besides these tiny little cramps in my uterus. And my back aches. I’m not excited because I’m scared, I’m scared that I will go through this again. I haven’t taken a pregnancy test yet because I don’t wan to get my hopes up. My miscarriage left me traumatized and I just want a family but I’m still hurt 😔. I put everything in God’s hands and let it be.
