I feel like I am going insane.

I've taken 6 tests, 3 have had vvvvvvvvvfls. If I am pregnant, I'd be about 4 weeks + 6 days. I have so many symptoms; constant hunger, occasional nausea(especially after eating), food and smell aversion, light cramps, gassy stomach, my nipples are sore and my breasts feel full. Has anyone else experienced early negatives with pregnancy symptoms and turned out to be pregnant?
