Is this for real? So happy, yet so nervous

Ch
Is this for real? It feels so faint for 15DPO, I took a test at 11 DPO and BFN....
We have been trying for 6 months after a chemical pregnancy with no luck. After seeing a fertility doctor he gave me the news that I have a uterine Septum and would most likely need to see another specialist to have it removed (my appt was at the end of May) to increase my chances of conceiving and having the egg implant into an area with good blood supply so that it could thrive... 
I'm so happy right now and so scared at the same time... I just hope it's a sticky egg that happened to land in the right spot and not on the Septum again.
