Am I pregnant ??

So I recently got off birth control because I was late taking a pill one day and started spoting which my doctor says is normal ,but what normally happens is after a few days it will regulate and become normal ,but I wouldn't stop spotting ! So I got off of the pill to give my body a break and the bleeding immediately stopped  however 2 period cycles later still no period ,I took 4 pregnancy tests from different brands and they all came back positive ...could there be any explainatiom other than pregnancy??? My doctors appointment is not for another week I have so much anxiety
