I'm unsure... Help?

What do you guys think?
My husband and I have been TTC for 2 months now.  My last period was on April 16th.  My expected period was April 14th.  It's been 33 days since the first day of my last period and I'm 5 days late (14-18).  I've tested numerous times but they came back with a BFN.  This morning I tested again and got that (picture attached).  Not sure if it's a BFN again or an exciting BFP.  The more I look at it the more POSITIVE it becomes but the more I think about it the more NEGATIVE it becomes.  I'm just crazy.  Lol.  I don't know if it's just me wanting to get pregnant and my eyes are just playing tricks on me or if I'm really not pregnant at all.  I won't be discouraged if I'm not.  I just would like to know so I can continue trying.  I also have a yearly check up coming up next Wednesday (4/24/17).  If AF doesn't come then, do you guys think it would be good to get a blood work done?  
TIA!
