I was doing the ovulation tests and I was reading them wrong didn't realize it till latter was first time using ovulation tests but I did have sex when I was ovulating. I have an app that tracks my period but it is saying I was supposed to get it today and than Dec 24th my question is when should I take a pregnancy test should I wait till the app says my next period is to see if it comes or should I take one sooner? if you would be willing to help that would be great thanks.
