Aleve and periods..

So ladies, last month i took aleve before my period for a headache. My period started and only lasted 2 1/2 days. I have a normal 27 day cycle. With my periods lasting 5-7 days. Wel i didn't think anything of it. Here i am 2 days late for my period and realized i took aleve 2 ago...could this medicine be causing my periods to be fucked up? I haven't taken a pregnancy text yet but i have great feeling im not pregnant. I have cramping on my right side but that's about it. Help?
