6 days late...

Hello girls! Well my AF was supposed to come on Oct 12th but it hasnt come, on the 11th I had cramps like it was coming but she hasnt show up. My boobs are tender and they feel full, i have been sleeping and feeling tired like a crazy, I have bloated & also i have back lower pain that usually comes with my period not before. Im scared of taking a pregnancy test because I am scare that it come out positive because of this whole dilema that I have with the “man” that I am in a weird friendship/relationship. Any advice girls?????
