Unprotected X, Plan B, Blogs, Preggers... Idk

** NO JUDGEMENT PLEASE, I JUST NEED ANSWERS*****

I had unprotected sex with my SO on during my fertility window ( according to the apps I use to track Aunt Flo). On this particular night it was my peak day for conceiving (realized it after the fact). I purchased plan B pill the next day. I read on the label and in some blogs that plan B doesn’t work if you’re in your fertility window or ovulated. So at this point idk what to think at this point...... I’m currently playing the waiting game. Aunt Flo is expected between Friday-Sunday (according to my apps). Right now I have a clear liquid CM with a very light flow. Normally by this time in my cycle it would be dry or thick & cloudy ( like lotion)... is it possible can be pregnant or you think the plan b done it’s job.?

FYI- this is my last time taking plan b, I had terrible side effects

Here’s my break down of my cycle details:

Last period: 3/23-3/26

Sex on 3/30-3/31

Plan B on 03/31

Update I found out I was pregnant on 4/27 via blood test
