I'm 16 days late, took a pregnancy test which said negative. Yesterday, (got bit by neighbor's dog and had to get a tetnuse shot while there they did another pregnancy test) also came negative. They said a blood work test would be more accurate but couldn't afford. Still haven't had my period. App says next period is in 15 days. Like idk wtf. We're trying but ugghhh *edit* yes I am 16 days late I keep track of my period constantly and it's always been accurate as well as going along with the app. I do not believe I am having a delayed ovulation.
