I know it's hard, but the more you are anxious about it, the more it will not happen because you're stressed about it. Yeah... as if I have anything to provide since I was and am going through the same things, thoughts and worry as you. We went through the whole IVF journey which cost lots of money and in the end we are still childless. Definitely heartbreaking.
My sister had tried to get pregnant for over a year. She swears that she got pregnant when she stopped eating sugar (all sugar!) and taking 100% live acidophillus (from the health food store fridges). She was quite angry that I would not do this, but I tried to explain to her that her husband had not undergone a vasectomy reversal. Not sure what your situation is... low sperm, female issues, etc.
I read something that might help you (we are going to try it ourselves), so send me a personal message if you want to more info.
