smtg embarrassing happened to me and i still feel weird abt it

this month i got my periods with the worst possible cramps that i had to take the day off from my office. this friday while i was coming back from office i took a rickshaw and sat beside the driver, by the time i got off and was abt to pay him i realized i stained his seat which we both noticed, i got super embarrassed and didnt what to do so i js paid my fare and left. its been 2 days and i feel so embarrassed abt it since i have always been very cautious abt carrying extra pads and spare pants.
