I got a positive pregnancy test but it was very very faint yesterday and today I took another and it was definitely darker (I will post the photos)  y period isn't due until the fifth so I'm kind of freaking out about a chemical. So if it's a chemical will the lines still get darker or is them getting darker A good sign that it is not a chemical or could it be a sign of either?? I'm just kind of freaking out over here LOL... this photo is yesterdsy. I'll comment with today's!!!
