I recently went on a one month trip from North America to Europe, for the purpose of a worldwide dance competition. I'm on the pill (Aviane) which is a low dose birth control pill, and I have a boyfriend of whom I'm in a sexually active with. The last time I had my period (15 days ago) it was only 1 1/2 days long, which is different from it's normal 3-5day range. The day after it ended I spotted once. And since two days ago I have been spotting now as well. Does this mean I am pregnant? Do I need to take a pregnancy test?

I'm a senior in high school and am not wanting a baby at this time. Could it have been from stress of travelling and such tight competition, and that the spotting is a way for making up for my lack of period when i was supposed to get it? My next period isn't supposed to come for a couple of weeks, but i'd rather know now than then. Also, getting used to taking my pill at the same time again has been difficult for me, as school has caused me to take it 4-5 hours apart from when i usually take it, and I haven't been taking it on the same time everyday, which could add to the problem. We always use protection, though we have experimented to feel what it was like without it recently, though we were responsible about it....

Can anybody help me?
