POSSIBLE PREGNANCY

I was wondering if anyone can help me please and tell me what this possibly could be I know it's discharge it's really white and creamy I was wondering if anyone has had this and been pregnant EDITED: I've had this on and off for a few days now I have eight days until my period so I probably wouldn't know until then I do know that you discharge more when your pregnant I've had cramping and head aches since 4 days after my last period

edited: I don't have a yeast infection
