Am I pregnant? do I have early symptoms? What are the earliest symptoms?

I have had a queezy stomach for about 4-5 days now oof and on during the day.. I'm bloated, and I've also noticed a slight change in my eating habits. Example: one night I ate a tv dinner that was good, the next day I spit it out becauses of the taste and the taste was the same. I don't get my period for another 1.5 weeks.... My periods are crazy, and even BC doesn't regulate them. I'm 21 and I don't think I'll ever be regular. I usually don't bloat like this and I though it might be a virus, but for this long? Plus I'm a projectile vomiter, so when I do get a virus I REALLY know it. No diarreha, and I had a slight temp increase. I've also been light headed. All of these signs point to the obvious but I don't exactly want to get my hopes up. This wasn't planned but it makes me happy if it is true. With all these symptoms, is it too early to take a test? A little help please!
