ClearBlue Easy Pregnancy Test?

I have a wacky period that usually is about 16 days long but it can very month to month but its never more than 21 days long and its never shorted than 14 days... ever. Well I have been charting my basal body temperature because I do not think I am ovulating and I want to have proof to show my obgyn. Well strangely enough I actually did get a very large spike in my temperature but it happened only 5 days after my period. So I just considered it a fluke. Well I have unprotected with husband just about everyday. Well 9 days after my last period I had another period again. Which is extremely strange. And it wasn't my normal period either. It just hit me one day. Normally I spot right before and my left side always gurgles the day before my period. It lasted 3 days. Well after that about the past two days I have been having some weird cramping on both sides. I usually never ever cramp during any part of my cycle. The only thing that happens is my left side gurgles right before my period starts and right after. Well now both sides of been randomly gurgling. My right side has never done this before. It was hurting around my ovary area and also on my lower backside where they would be as well. Friday my ovaries felt weird and the best i can describe it is like a floating feeling. Well yesterday I took a clear blue easy early pregnancy test just to make sure i wasn't pregnant. I figured I wasn't cuz I don't think I can even get pregnant. Well I checked it about 3 minutes later right as the test line was appearing and it said negative so I put it aside and thought nothing of it. Well now I went to the bathroom like 4 and a half hours later and I happen to glance at the test stick in the trash and the vertical blue line that appears if you are pregnant was there. It was pencil thin though and not as fat as the "test" line. Is it possible that I am pregnant? I don't wanna go waste more money on a new test. The test says don't read the results after 10 minutes but i was thinking maybe is turned positive after the 3 minutes I looked at it. My husband thinks this is just a fluke. What do you think?
