Getting my hopes up

I've been ttc for 2 years, but actually "trying trying" the last 5 months using this app and ovulation kits etc.... every month my period hits and I just cry. I see people every day accidently get pregnant that don't want kids....and I have an amazing husband and we want kids. I'm super jealous. :(

Now this month my period was suppose to start the 14th, and I haven't had anything yet, took a test...negative. my periods in the past have been off sometimes a whole month....but the last 6 months my period was on time.........ahhhhhhhhhhhh I really hope I'm pregnant!! If not.....should I go to the doctor just to make sure nothing is wrong
