So my period started today and it was very light which is unusual but there was very little blood on the pad and i only see blood when i wiped and also this happened to me when i got my period last month ?

It happens sometimes: Many women have occasional variation of their mucus discharge, some spotting between periods, a heavier period, a lighter period, a longer or shorter period, or even a missed period. Having one of these symptoms doesn’t necessarily mean there is a medical problem, but a call or visit to one’s primary care or Ob-Gyn doctor is a good idea if there are other symptoms or if one is just very worried.
