1 week late???

Faith • Live. Laugh. Love. like today is ur last day.

I'm 1 week late, nauseous, bloated, cramping, and always hungry. Got mood swings from hell according to my fiancee and I'm constantly tired. We also had sex right before my last monthly but he pulled out but we didn't use protection.

I haven't tested yet in hopes that my monthly (period) will show up soon. It usually comes around the same day or a few before/after. What should I do?
