Late.

I had my period from Jul 5 to the 8. I took a plan b some time the following week as a precaution. Then a week after that i had light spotting for 3 days. Since then I've taken 3 hpt, all neg. (Took one test each week). I took the last test this past Saturday. Should i have counted the spotting as a period which would mean that I had two periods last month & I'm not late just yet. Or not count it which would mean I'm about 9 days late. And with all the neg hpt i should be able to rule out being pregnant. I've never missed a period before unless i was pregnant so irregularity is fairly new to me.

I would just like some input, no negativity please.
