last month a few days before my period my boyfriend fingered me, he had dry pre-cum on his fingers. my period came and went as usual, half way through the month i got a strange light pink discharge when i wiped which i had never gotten before. i started to worry about pregnancy, but i just put that down to ovulation. this month i think my period may have come late, (unsure because it comes at a different time each month but it just seemed a bit later this month) i had cramps for the week before it came, it was normal for a whole day with usual cramps and stuff, but then for the next 4 or 5 days i just had bright red spotting and cramps still. what could this mean?
