Period late and BFN! Please help!!

La

I’m on provera 10mg to help regulate my period and it has made them EXTREMELY regular. 24th of every month or a day early. Never late. But now I’m 3 days late. And I had a BFN two days ago. Has anyone gotten a BFP after this? I’m betting I just ovulated late but I’m not sure. Also my logging isn’t accurate since I was avoiding my apps this month. They just make me worry too much.
