I should be starting my period soon, I'm having cramps and everything. After I used the bathroom, I whipped myself and there was a bit of blood. I stuck my finger up there to check and only found a little blood on my finger. My flow is usually heavy and comes instantly, is this lightness normal?

Normal is subjective. What may be normal for you may not be normal for another woman. I don't know your medical history, so I don't know if this is normal for you.

Most likely you are about to start your period. Are you trying to get pregnant or don't you want to be pregnant?
