need your opinion on chart

[LindsayDawn]

According to Fertility Friend, I ovulated on CD12. According to TCOYF, I ovulated on CD10. Which do you think is correct? Because I had a tiny bit of spotting yesterday (CD16) and I don't want to get my hopes up if that was only 4 DPO and doesn't mean anything. :(

Thank you for your opinions!

I guess next month I'll use OPK so I'll know. (If I'm not pregnant this time.)

I guess I don't 100% understand the TCOYF chart -- it seems like they have your "fertile window" as the two days before and the three days after O, but I thought that O occured toward the end of your fertile window, if that makes sense? (So it kind of seems like you had great timing according to either method even though it looks like they're figuring it differently, since FF says the "fertile window" is the 4 days before and 1 day after O.)

FWIW, I had cramps at 4dpo (according to FF, but only using OPKs) and I got a BFP today

Just wanted to say congratulations on your BFP! Hopefully mine will be in February. You and I are really similar - my little man was born 5/23/10, and I had an early loss in October too. This month will be my 9th cycle trying.
