Pregnancy Test

Felicia
Took a pregnancy test today, 5 days out from my period and there was a very faint positive line. I'm talking like, you gotta really look at it to see it. I plan to take another one in a couple of days, but what do you guys think? Pregnant or not? 
Update: I've also had spotting the last couple of days (not normal for me) and very sore breasts.
