INFO: 5-6 DURATION USUAL MENSTRUAL CYCLE OF 32-33 OR 34 DAYS DEFINITELY NOT 28

I got my period like 2 days late and i cant smell the usual iron smell, i have cramps yes,sligjtly nauseous more like i feel like i am starved and hungry . i dont know when i ovulated exactly but i didnt have sex. I washed semen from my hand then washed my private part after peeing. I dont know if i am pregnant i am super scared! I tested negative in march 8 (18 or 19 DPO if i ovulated earlier) then at night i bled like that now its been 2 days ..... if my fertile window begin in 14 then i should be fine right since sperm can only live 3-5 days. Also i had bleeding like that tissue 3 or 4 tissue with that slight bleeding+clots. I dont know why its not heavy my cycle is always heavy! But this month i was very stressed. Also it sounds late to be implantation bleeding.....WHAT DO YALL THINK ???????
