I took a pregnancy test and I waited for two minutes like it said too and it came out negative. I kept it with me because I didn't want anyone to find out that I took one so I kept it in my purse. I took it out of my purse hours later and it showed a faint line acrossed it. Does that mean I am pregnant? Or did keeping it in my purse affect it? I know this is a stupid question, but I just want to make sure.
