Some women just don't test positive on HPT's, ever. I suggest you call up your doctor and ask him to schedule you for a blood test at a local lab. That will conclusively tell you if you're pregnant or not. If you're not, you can see your OB/GYN and he/she can determine why you're missing your periods and getting pregnancy symptoms.
I have heard of girls not having their period because of excess physical activity, eating less, or heat.
