Natural ways to get pregnant

Victoria
My husband and I have been trying to get pregnant since September 2007. Did the test to check tube blockage in July 2008 and got pregnant the next month. Found out August 2 I was pregnant and lost it in the 6th. Fertility treatments soon started and haven't been able to get pregnant since. Couldn't keep scoring the expensive meds so had to stop. All I was ever told is I needed extra help. Was wondering what anyone else had had and worked for them. I will be 36 next month so feel my time is running out. It is getting depressing. Working with kids doesn't help, sometimes it makes it worse, daycare teacher. Any help or advice would be appreciated, thanks!
