Not sure whether to celebrate or cry

Well I'm spotting a tiny bit tonight, so one of two things is happening:

#1: Fertility Friend was right about my ovulation date, meaning that I'm actually 2 days further along in my cycle than I thought, making this is my usual 12dpo spotting leading up to Aunt Flo showing her very unwanted face on 14dpo; or

#2: I was right about my ovulation date and this is potentially implantation spotting.

I know which one I'd like it to be, but tomorrow we shall see which one it actually is...

P.S. I just removed my O-date override on my Fertility Friend chart, and suddenly FF is agreeing that I probably did ovulate on CD13 (it wouldn't do this two days ago, so I'm not sure what's changed since then?). Ugh. I really have no idea what to think!
