Feeling so disheartened

I am feeling soooo disheartened. DH and i have been ttc since march and so fat nothing has happened. My cycles since march have been pretty regular (29-33 days), we BD frequently as we are newlyweds (married in march). I dont know why its not happening..i believe in God and realize that it will happen when the time is right bt how can i overcome this feeling of incompetence and failure?
​Our family and friends are now asking if there js any good news and this is further adding to the pressure! I dont know if i should get a fertility checkup done or not..everywhere ive read it says to wait a year before even considering getting a checkup. I keep imagining the worst possible scenario and end up in tears. :( ive wanted a baby for a long time.. 
​Any tips on speeding up the process will be appreciated as will be any support. I feel sooo low :(
