Not understanding what it is. My doubt!

Hi my last period date is 18/10/23 my cycle varies a bit like 26 days cycle 28 days cycle etc . Today is my 27th day of cycle I was having severe pms symptoms on 23 day &25 day of cycle but I didn't get periods I am dealing with uti & vagina itching and on antibiotic so switched to cotton pads I wore a pad for safer side I have never seen this type of colour during my period it's somewhat pink I usually get dark red during my periods , and I could barely see it on pad when I wipe with tissue I don't see any bleeding even during shower I didn't see blood nor my clothes nor stained if I don't wear pad Is this period or something else or is it cotton pad bleeding looks like on it but I had severe stomach ache in morning like periods since not understanding what it is Am attaching pic I hope u don't mind sorry if it's awkward Hope you clear my doubt Thanks
