Implantation bleeding or period!?

i was supposed to start my period yesterday. I’ve not had any cramping what so ever. All my pregnancy tests have came out negative. My last cycle was 9/21. Today after work i came home, i noticed snot like discharge that was stringy As well as cloudy and a little yellow with no Odor. Kinda like when you blow your nose and it’s kinda stringy. Shortly after i had water light pink blood. Again no cramping and I’ve had negative pregnancy tests. Plus i know i ovulated already because i had an ultrasound done which showed the ring of fire ovaries and showed that ovulation just passed. Normally before my period my cramps will be bad for a few days and I’ve had none. Plus the first day of my period is super super heavy with large clots. I’m typically laying in bed crying the first day. I’ve had none of that.
