What's the probability of pregnancy in this scenario?

Although every person is different, and there really is no way to answer in a simplified manner...what is the likely-hood that someone that is 10 days late for their period, 20-24 age range, regular 29 day cycle, unknown ovulation or luteal phases, but had a negative pregnancy test the day before the period was expected...to be pregnant?
A week, possibly week and a half before the period was due to start, there was some brown and very light pink/orange spotting.
Junel 1.5/30 was used (although in a typical fashion, not as intended), as well as the "pull out method"...

You very well could be. I would take another test. Or you could just be having a weird period.

I agree that it could have been too early.  I would wait a week from the last test and take another one.

Sorry, what is Junel?? The pull out method, also if not effective at all. Since you tested the day before your period was due...could have just been too early to detect the hormones. I would re test now with first morning urine, you are late enough now that it should show up accurately enough.
