What do you think?

Taken 3 days before my period, I have symptoms. I know I shouldn't have but I took a test. Came up within a minute. It looks like it's a BFP but could it be false? Have any of you lovely ladies had this happen and it end up being false or chemical? 
Hubby and I have had a rough run baby making :( so I'm finding this all too good to be true!
