My period normal come on every 23 days but this time my period came on the 24th day. Well I'm using this app on my iPhone call period tracker that keeps up with my period times and when I ovulate.well for one I don't know how accurate it is because I've done a ovulation calculator online, several, and they all give me different ovulation times.in July my period started on the 3rd ended on the 7th. Then in August came on came on the 1st ended the 4th and the calendar say I'm fertile 6-1o ovulate the 11 and fertile the 12th. Well I had unprotected sex with my boyfriend today(the14th) and I'm wanting to know is this stuff accurate and could I still get pregnant IF the app was right, with me doing some 2days after supposeofly ovulating? Because I am trying to conceive.
