Advice, too early for a test?

My period is about a week and a half late. I've been cramping for about 2 weeks & usually get cramps the week of my period or a couple days before. These cramps are also different, they come in a little strong then I feel a type of numbness afterwards. Also have been nauseous & very ill feeling in the morning especially after coffee. And a few other symptoms. My bf & I do have u.p.s and I am not on bc, he has ejaculated on my vagina and possibly a little inside.
