6 days late

So girls, my period came on the 6th of March. I have a short period so it is usually ever 22/23 days. A week after my period I started having a weird bleed. Not enough for a pad or tampon but maybe a pant liner which lasted a few days then went away. My period is now 6 days late, I’m getting like milky discharge abit and like sort of like a pinching on like my left ovary??? Has anyone ever experienced anything like this. My partner and I are TTC for about 7 months??
