Ummm app wrong?


Hello new here I've been TTC for 6mos, I was only using the app at first when my bff suggested I use the app and ovulation I did one on the day the app said I was ovulating and it was BFN. Yesterday I did one because I was feeling frisky, so before me and MDF laid down I took another ovulation test and it was BFP, I'm just wondering if this has happened to anyone else?
