I used to poas like 4 times every month at least.. Not even at the right times! just cause I wanted to and jic. Then one night (when I wasnt even due for AF yet) I poas and then saw a very very faint second line. I almost fell off the toilet!!!! So I went and bought another test... Right away BFP, now my BFP is attatched to my boob n won't go to sleep!

So randomly testing can bring surprise bfps! I say go for it! Lol
