Am i preggo or not?!?!?

so me and this guy have been having sex since february. we only used protection the first 2 times. i was on the pill in the beginining but havent been on the pill for the last 3 months. hes never come inside me. i was suppose to have my period on june 7, but i still haven't had it. im having some symptoms. when i wake up in the morning i feel nauseas and i stay nauseas all day long. ive barely been eating and when i do its weird stuff like cinnamon rolls and chicken breast lol my lower abdomen was sore a few days ago, but since then it hasnt hurt to bad. ive noticed ive been going to the bathroom alot with dierrhea which is unusual for me considering i only go 1-2 times a week. i took a HPT (the walmart version) and it came up with a faint pink negative line.. so if the test said im not pregnant, but im having all the symptoms, and im a week&a half late, am i pregnant or not!?!!?
