My period is already 5 days late and i'm having little to no discharge. no pms signs too. is there a possibilty that i'm pregnant?

May be: Do a pregnancy test 7 days after your period is missed, if negative, repeat it in 5-7 days. if both these are negative, then you are not pregnant.

You need preg. test: If you had genital sexual intercourse with a healthy fertile man about the time of ovulation, the best way to get an answer to your question is by having a urine or blood pregnancy test..
