We decided to start TTC so I have been off BC for about 5 weeks. We had about sex two weeks after stopping my BC.(he works away from home so we do it when we can)  It was the day before my fertile window according to the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a>. Now my period is 3 days late. I took two pregnancy tests last week (4 and 5 days before my period was supposed to start) They both came back negative. I am considering taking another test today since my period is now 3 days late. I'm just wondering what are the chances of my period only being late due to just getting off BC (this would be my first period since I stopped).  I had irregular period before BC and I have consistently been on BC for 5 years.
