Spotting after possible period

I had a period Feb 17-21, on February 27 i had an encounter where my boyfriend got off and after cleaning himself he touched my vulva just to feel how wet i was, there was no inserting at all. Then i got what i thought was my period March 22-27 i remember using multiple pads. i wasnt worried at all until april 2-3 i noticed pink spotting. And yes i know a woman cant be pregnant if she has a real period but that spotting just made me overthink it that was actually my period. I had terrible cramps and i do remember it bright red. I just keep reading about implantation bleeding and how it can be confused with a period
