Scared I’m pregnant.

My period is 14 days late, both my roommate and I are both super late and pregnancy test have come up negative. I took a digital one at 3 days late, it was negative. Someone suggested the First Response Early Response because it very sensitive, I took it at 10 days late, and again today at 14, and they were still negative. I’ve been having some cramps, and also pooping along, which is something I normally do before a period, but yesterday I felt a little nauseous and today it feels like I’m going to throw up, which is why I took the test. It could be someone I ate, or I could just be getting sick, either way, I don’t really want a kid right now.

Help? Advice? Idk.
