Spotting???

🌸🦋

I had sex a few days before my period & he came in me. Now I’m on CD 14, and according to Glow I’m supposed to ovulate tomorrow, but I’ve been having weird pinkish discharge/spotting for about 2-3 days now? It only happens when I wipe and I don’t smell anything off or my vagina doesnt feel irritated, so I know I can rule out STD’s. Is this normal?
