Help me

I had sex June 20 but my ovulation week start the 22- 28 .. but on the 26 I had this pain on my lower stomach that couldn’t take it took my breath away so I called my doctor because I notice my panties seem wet . Then I wiped and notice light pink discharge then later on I saw this in my underwear I no longer had the pain went on by my day few hours the pain came back n I couldn’t take it for 5-10 minutes Out 1-10 it was a 10 but after that no more pain or discharge. Don’t think it could be implantation bleeding because according to the app I was ovulating my cycle come ever 30 days I’m so confused .
