Are dizziness, nausea, mild cramping, and white discharge signs of pregnancy?

I've been having mild cramps ever since my period two weeks ago. I've also noticed a white creamy discharge for the past few days. The dizziness has been occuring the past three days mostly in the morning. I won't even move or get out of bed. I'll just wake up and the room will be spinning. It lasts most of the day but is over by the time I go to bed. Nausea also accompanies this but it might be because I've been so off balance. As i'm writing this, even, I feel dizzy randomly. If i'm pregnant, I could only be between four and five weeks pregnant. I should be on my period right now, but due to the fact that I took the Plan B pill three days after unprotected sex I had a period a week and a half early.

i think the best way to know is to take a test or go to a doctor. you can do it anytime of the day.
