Insecure

My AF was supposed to be Monday. I haven't had much of any symptoms that AF is coming. So I'm 5 days late and I'm usually not. Did a hpt Tuesday and Wednesday both BFN. I'm gonna try and wait until Sunday to retest. I had a MC in. 2010 and haven't been pregnant since. I didn't realize I was pregnant until 12 weeks. I'm scared I'm not going to know and have another miscarriage.
