Plan b..

Had unprotected just under 72hrs ago and I took a plan b this morning 8:43 am. 3 days ago he came inside me around 1:40am.

My tracker says I ovulate today, which I predicted would be today or tomorrow but it’s just an estimate right ??

So I’ll be okay? Should I worry or is it going to be okay? I barely have discharge because I am on accutane so it’s hard to tell by CM if I’m ovulating or not.
