Missed period no positive EPT???

Caitlyn • 36, happily married on 8-14-15💍. MC 1/26/19 👼 Pregnant with my 🌈 👶🏼.

I’m 8 days late and still don’t have a positive EPT. I haven’t been this late since my miscarriage Jan 26th 2019. Any insights? Oh, and am experiencing pregnancy symptoms like exhaustion, lower abdomen cramping/lower backache and a bit of nausea. My skin has always been super clear and I’m starting to break out.
