Test question

I'm curious because I was reading some stuff and it's yes and no. I took a test a few days ago and a few hours ago, but I still have them stuff in the drawer(don't want so to see me throw them away b/c I don't want him to be sad). They were both negitive but when I looked a few mintes ago they were both positive. I've done that before and I've never seen them become positive? I've just been reading that it was a bfn the hours later it was bfp and they did end up pregnant! But I know you're not suppose to read past the time frame. Just curious on your insite! I will be testing again in the morning or wait until af next week(thought it was going to be yesterday or today)to be over with so we can ttc again!
