BFN two days before period is due 😞

I've done a test today (2days before period is due) and it's a BFN. We have been trying for months but this month felt different, I ovulated and did the deed at the right time! I don't feel like my period is coming, I usually get very obvious signs but nothing this month. Has anyone else had a BFN before their period was due and then got a BFP a few days later?? Hoping and praying I do xx
