Plan B

My boyfriend and I were planning to wait until marriage to have sex so I got off of my birth control this past fall. Last night he stayed over and we got caught up in the moment. He got me off of him before he came. I’m not on birth control and my periods are irregular. The app I normally used to track my cycle told me I was supposed to be on my period already this week but due to them being irregular I wasn’t too worried I hadn’t started until today. I tried putting it into a different app and that app tried telling me today is supposed to be a high fertility day and I’m supposed to ovulate in 2 days. I took a plan b around 9 hours after the unprotected sex and took a clear blue advanced digital ovulation test and it showed me I had low fertility today. He told me he pulled out before he came but that that’s not always reliable. I have a yearly checkup with my GYNO on Wednesday and I’ll talk to them about it, but like am i in the clear? I’m freaking out!

Update: took another ovulation test first thing this morning and again said I have low fertility but I read somewhere you’re supposed to take it in the afternoon?
