I don't track ovulation but af due Thursday

Alexis

So I came off the pill in December and have been trying since then. I only go by when the app says I was fertile or ovulated. But me and hubby have sex every other day to every 2 days from the stop of my period until the next one. My periods have been regular about every 28 days and I bleed for about 6 days. I took a test yesterday and bfn. Could I still be pregnant?
