Late period?

Stephanie

I kind of forgot I was supposed to get a period and didn’t check the app til today and I MISSED MY PERIOD, this never happens. Hubby and I don’t use protection but he never finishes inside me. I took a test and I’m pretty sure it’s negative. I have super regular periods, I don’t get cramps and I don’t spot so I don’t know what it could be. Am I testing too soon? It’s been 19 days since my ovulation.
