I don't know what to think? 😩

I took a test on the first day my period was due.. I wasn't even going to because I felt like my period was due imminently.. Then got this...
But I still feel as though I'm due to start any minute.. Could this be a false positive? I took one later on in the evening and got the faintest of lines? 
I really don't know what to think because I still feel like my period is coming! This is our first even slightly positive test in 13 months and this is our first pregnancy so I don't know how your supposed to "feel" ? If that makes any sense! Just hoping for a bit of advice? Thank you x
