I started my period which seems a little early!!!! please help!!!!?

Okay so I stopped my period about 2 weeks ago. This evening, I went to the restroom and when I wiped, there was a little pinkish tint there that has lead me to believe that I have either started my period or ovulation. Seeing as how I just stopped my period 2 weeks ago...I would guess that this 3rd week is ovulation and that next week, the 4th week, would start my period. Which the timing is perfect. But still a little early for my norm. I also had an today. Which may have contracted some blood. Or perhaps jump started my period a little sooner than normal. One of my worst fears is that someone is going to come into my apt while I am sleeping and inject hiv infected blood into my .but I checked the pj pants I wore last night and no blood. Is everything with me normal????
