So the past couple days I've been cramping with usually means my period is coming. So today I "think" my period came, I am bleeding but it's lighter than usual and there are no blood clots. I'm 17 and sexually active from time to time but I do always practice safe sex. So I was wondering is this is normal for periods and later through the week my period will get heavier and such or if I'm spotting and should take a pregnancy test.
