can it be IB or period ?

Hi 👋🏼 I had unprotected sex on the 22 and 26th of may ( during my ovulation days ) my period is not due until the 8th or 9th . Last night ( around 1 in the morning ) I wiped and there was light pink blood on the toilet paper , this morning I got up and it was a lot more ( didn't fill up a pad , just when I sat down a lot came down in the toilet ( sorry tmi) . Now can this be implantation bleeding !? I'm also cramping .
