Pain in side 3dpo

So I ovulated fri/sat (tracked and had the egg white 2 days beforehand) Bd thur, fri and sat.

And since Sunday I have sore pain in my left side, it’s not bad enough to need painkiller but it’s sore when I pressed on it and can almost feel it when walking/moving.

I have had pain there before 2yrs ago and it was a cyst that ended up going away itself but I was checked for cysts in July gone past and ovaries were all clear. I am really hoping to get pregnant again🙏🏻

Has this happened to anyone and got a BFP? Or any advice pls 🙏🏻😬
