Period or spotting?

Megan

This is odd for me I am a heavy bleeder since off depo and had my period last month (sept 4th) my fiance went away on Sept 8th so unless I was pregnant before he left and what I tho was my last period in Sept wasn't one at all and misread it can't be that . I was spose to start my period yesterday but I only had this bleeding the once then nothing but light stains on my pad
