Will you please take a look at this one? Could I be pregnant?

It sounds like you might b!!! :) If you are spotting and stuff, that's not really normal even if you just got off the pill. A few years ago, I went off BC and my period was heavy/normal but came at different times. You should go to a doctor right away, as the HPT may not have detected the HCG yet, because it might be too weak. Good luck, and baby dust!!
