I had sex on sept. 24th and he did the BOMB in me. I don’t know if the app is right about the ovulating part. I probably ovulated later IDK! I DO know that this app is always accurate on when my period starts. I wouldn’t say stress is the problem because let’s be honest here I STRESS ALL THE TIME and my period is neva late. I was suppose to have my period yesterday. I waited all day for it and it hasn’t come. I took two dollar tree tests today and they both came back negative. What’s really up?? If I am pregnant it would be about 3 weeks and 2 days. Would the dollar tree detect that early? Am I pregnant at all?
