Pregnant, something serious, or worrying for no reason?!?!?

Well the light period could be implantation bleeding. Especially if it was way lighter than your typical period. So you very well could be pregnant. Also with all the other symptoms. Even if you could pick up a dollar store test, that would do it. There all pretty much the same, no matter how expensive or cheap. That one that I took when I found out I was pregnant. I don't think anything is seriously wrong. If your not pregnant it could just be an off period. Try to test ASAP. (: Good luck.
