The last time i had my period was at the end of April going into May. About 2 weeks after it was done, i had sex without a condom, but he never came. I usually have irregular periods so when i didn't get my period for a while it seemed normal, but i still haven't gotten it. I took a pregnancy test and it came out negative. I haven't gained any weight, in fact, i lost about a pound or two, my appetite has not been good and i don't get hungry anymore. i am sort of bloated and get mild cramps but they usually go away within a few minutes. I have been extremely stressed out recently and think maybe this is the reason. My question is why haven't i gotten my period??? Any thoughts??

I am sure stressing about it doesnt help your body. But the best advice is just find a doctor and let them help you out. We can give you all the advice you want but a doctor would be best.
