5 Days until period!!!

For the past week, I have felt fatigue, stomach cramps, heartburn & indigestion, and just today, an increase in CM mucus; I had to change underwear. It's also, white and creamy. I woke up this morning and felt so nauseous, without vomiting. My period is due in 5 days and I'm anxious to find out if I'm pregnant. Is it too early to test? And did anyone else experience this and test positive? Thanks!
