Sharp pain ?

If I ovulated when glow says I did than I’d be 7dpo but I could’ve ovulated earlier or later idk but last night I got a sharp pain on my ride side back lasted maybe 3 sec and a couple times today I’ve felt it again has anyone got there BFP and had this happen ? 🤞💖 (ik it could be anything so don’t be negative I would just like to hear if this has happened to anyone before getting there bfp)
