I don’t understand what’s happened here. I know I ovulated due to temperatures. However, my period has not come. I thought it would come yesterday because of my luteal phase length, and so I put a tampon in and there was just a smear of pink blood, with nothing since. I think FF got my ovulation day wrong based on temps but my period hasn’t come and now I don’t know. And my BBT has dropped, but still no bleed.

Does anyone know what is going on? Please have a look at my chart below. I did a pregnancy test yesterday and it was negative. Please help, I’m stressed by this!
