So uhm possibly pregnant help?!

I've been experiencing a slew of symptoms started after I got out of my last fertile window. The symptoms started out harmless like nausea and increased appetite that I held off on. Then I started vomitting and having headaches with intense cramping and lower back pain, sore and tender breasts to the point I can't wear a bra without cringing. I've been peeing more and have noticed increase in gas too and had this weird craving for BBQ chicken and some garden vegetable rice and I ate it enough to tide me over but i still am craving it.
