Last Tuesday I had a little spotting. I thought I started my period but it went away that same day. I still have cramps like I would on my period. Does anyone know about that? And also I took a First Response pregnancy test and I did everything correct but, it has one dark red line and a very slight pink line. Even though it says one line may be lighter, how much lighter do you think it would be to be pregnant? It seems like there's already two lines there, and the urine just goes through both. Help!?
