I don't know exactly when or if I ovulated, but if I did, I know it wasn't early enough for a 19 day cycle (I can give details if needed). So I don't have a period due date, but I've had very light spotting on and off for the past five days (cycle days 19-23) that could possibly be implantation bleeding. It most likely isn't--I doubt I'd be lucky enough to get pregnant this cycle after only one confirmed ovulation in two years--but IF it is, when could I test and expect an accurate result? I know IB is often short-lasting, but I've seen the occasional story of someone spotting for up to a week or even two and getting a BFP, which makes me more hopeful than I probably should be. I'm probably more hopeful than I should be about even having ovulated :-/. Should I wait until any spotting is completely gone and then test?
