What should I do?

My period is to start in 11 days... But I'm very anxious to take a pregnancy test now. It's been about 3weeks since it first happened .. & He hasnt been using the pull out method ever since then either.. so should I just wait it out ? Cus I'm pretty sure I might be. I have had a few symptoms but could be mistaken as allergies ( so I've been told ) I really wanna know but dnt want to be too early then be a false neg..
