I don’t get my chart at all. I know I’ve only been using a normal thermometer so it’s not very clear but my OPK said I had a peak result on CD25 and the FF app confirmed ovulation but said I ovulated on CD24 so around the same time. So it makes me around 13/14dpo and I’ve had brown spotting for the last 3 days so I’m guessing my period is on it’s way but why did my temp rise again?

I’m not 100% sure when my period is due either as I stopped birth control January 25th
