Am I pregnant?

So I’m not due for my period for three more days. I normally never get nauseous before my period, and I am on birth control (the pill) so cramping is light. I missed a pill due to forgetting it at home one day after I had sex and now two weeks later I feel like I’m going to vomit my lungs out and my intestines are cramping up worse than any period cramps I’ve ever gotten since being on the pill, I haven’t tested because again my period isn’t due for three more days but should I test now?
