How many have legitimately had implantation bleeding?

Kira • TTC 1st for 15mons and I finally had my BFP!

When you look up implantation bleeding it says that only 1/3 of women will experience this to some degree. But here it seems like every women is looking for it or questioning if they have it.

I’m asking because today I’ve had some brown discharge. But I’m hesitant to read into it 🤷🏻‍♀️ I’m having other symptoms of a possible pregnancy at 12dpo, but 8months of TTC and 1 MC leaves me on the pessimistic side of symptoms.
