Question. ...

So I took a walmart pregnancy test this morning (13 dpo) and after the 3 minutes I saw a super light pink line... so i took it to work with me which is about three minutes from were I live, so by the time I got there it had been about 15-20 minutes. Well I was fixing to show a co-worker and to my surprise I could see a more light purple line...it was kind of smeared almost to the control line ...has this happened to anyone and was it a bfp?? This will be my rainbow baby :)..
