I'm right there with you girl! I dunno how accurate FF is with my chart either bc I'm only 8 weeks PP and just started charting a few weeks ago and temping two weeks ago. No AF and BFing. It says I'm 4 dpo!
The thing with your chart is you have dotted crosshairs which I think means FF is unsure...also isn't counting your dpo. Looking at it, it looks like you could have Oed when FF says...have you tested? CD 19 looks good too. Hard to say girly! Guess only time will tell, but I would test!
There's still a chance of pregnancy. Interested to see tomorrows temp and/or test results!
Sorry I wasn't more helpful!
Good luck!
