I need some advice

Brey

So please hear me out, it may seem wrong but.. My fiance is finishing in me but so far i havent had the % chance isnt high but He doesnt want to have a baby and tells me, you better not get pregnant. But i know its wrong of me but I dont tell him when my chances are highest so far its been a 3% chance. I have missed my period but last month I took a plan b pill so i am guessing thats the reason, took a test came back negative.

Please no negative comments.
