I must know! AM I pregnant ?"
Wouldn't it be nice if pregnancy could be diagnosed online going only by symptoms? It would save a lot of women time and worry.
Sadly, pregnancy can only be detected with urine, blood, or an ultrasound in later pregnancy. Since we don't have access to any of those things online, we really can't tell you if you're pregnant.
You'll have to do what every other woman on the face of this Earth does, and that's wait, and then test when your period is late, 2 weeks after it's late, using first morning urine. That's really your only option.
Good luck.
