I'm Wondering If I'm Pregnant. I Have A Lot Of

I'm wondering if I'm pregnant. I have a lot of the symptoms, nausea, I'm tired all the time, things smell different. My aeriolas look different and there's these bumps on them. Mood swings. Light cramping in my lower stomach area sometimes. I've taken home tests and they've all come out negative but I just feel different than usual. I've read numerous arcticles and online blogs and such about women having tons of pregnancy test in there 5 weeks and they don't find out till there anywhere between 6-10 weeks.
