Ovulation Bleeding

We have been ttc for a few months now and a two days ago I noticed brown spotting. Yesterday was pink spotting- the tiniest amount and today I’ve noticed a tiny, tiny brown bit in my pants (sorry tmi)

Yesterday was the end to my fertile days (as the app suggests) and it is no where near heavy enough to suggest a period starting. I’m just wondering if anyone has had this and then lead to a BFP?

Thanks.
