How many days should I wait to test?

I know it seems crazy but I’ve felt that I been pregnant for a couple days now. My period is suppose to arrive in a week exactly. I don’t quite know when I would have ovulated but I know I had unprotected sex a lot this month. My symptoms include: heartburn, frequent urination, extremely tired/exhausted, fatigue, a craving of cheddar cheese since 4AM this morning. I know it’s crazy but I have been having vivid dreams in which woke me up last night in a panic. Feeling weak & hot to cold flashes. Any advice would help out a lot!!
