Period tracking? I'm lost.

I know this sounds silly... Buuuut. Should i count a little spotting as a period? Or keep going off of the same cycle I've had for almost a year? I have my normal period starting around the 13-18 of each month. Got my birth control removed last month. And stopped the pill. At the end of May i had spotted for a day or two, not too heavy, not extremely light. Should i go off of that for tracking or...? I haven't had a period for almost 4 years, except for the past 8 months and I was on mirena. But now I'm not. Any advice? If so i should of started my period two days ago from last month... My boyfriend & i are trying for a baby sooo.
