SO tired of trying! I feel like it is never going to happen?

i would suggest to stop worrying about it. Stressing yourself over getting those two lines makes it almost impossible. I tried of 18 months and the first month i didnt do any OPKs or BBT. I just completely didnt worry about it, i got pregnant. I know its hard but just look at it this way..it will happen when its meant to happen. Good Luck.
