Help! Faint negative on PT

Meghan • Newlywed. Considering pregnancy!
This may sound dumb but I'm a newlywed so this whole pregnancy thing is new for me.  I've been having (what I think are) pregnancy symptoms for a couple weeks now and I don't think they're period symptoms bc I don't usually have any. I'm currently on BC and was supposed to have my period last week but skipped it because of vacation, so I technically haven't missed a period. I took a PT yesterday (a |negative or +positive one) and mine was a very faint |.  Is that possible?  Should I take another test? Is it negative? No idea what to do. Any help for this newbie is appreciated!!
