My first time taking a test...

I don’t want to get my hopes up too early and I don’t want to tell anyone yet...is this a BFP (well, blue really)?! What do you guys think? I’m 13 DPO and tomorrow is supposed to be my missed period, so I’m planning on doing another test in the a.m. I’m so nervous and I don’t want to tell my husband until I know for sure!
