Cycle day 1 or not? TMI maybe

I am suppose to call the fertility doctor on cycle day 1. Well my periods are always so random, sometimes there is never a heavy flow sometimes there is. I had mainly just brown from Thurs until yesterday when some drake red finally made its way to My undies. Since then I haven't really needed a pad/tampon but there is red when I wipe. Should I count yesterday I day 1 since it was finally bright red and seemed more than the previous days? I did call the doc yesterday but in wondering if I should cancel my 3rd day testing tomorrow or not.
