Ok, here I am a 33 year old. Been having a period for over 20 years now, but now that I'm finally ttc I really need help breaking dow when day 1 is.

A lot of times I will have either spotting or maybe it's just very light bleeding for a day or two before the headliner make her appearance.

Should I count those spotting days as day 1 or when I have to start wearing a tampon as day 1?
