Confused...

Chelsea

Sooo my period was supposed to start nov 23 on this app and the 22nd on another app I haven't started so I'm now 15-16 days late..... butttttt I have taken 6 pregnancy test and they have all been negative... 😔 so I'm just wondering has this happened to anyone else?? How long did it take for you to get a positive? Or did you finally start??
