8 days late?!

Krystal

I’m 8 days late and my period is NEVER this late, early maybe but never late. When I got pregnant with my son, I didn’t find out until I was almost 13 weeks pregnant. I’ve taken a test already and it was negative. Is there a chance I could’ve gotten pregnant only a few days before my period and that’s why I haven’t produced the HCG hormone? Or does anybody have any suggestions?
