I'm keeping my fingers crossed for you, Retro!
It's interesting reading about being told to relax all the time. Don't worry about stress! Regular old worries about getting pregnant, and if you will ever have children, are perfectly normal and do NOT affect your fertility.
Ignore those people who tell you just to relax and stop thinking about it. This is not their problem! The only thing that could actually affect you is serious stress, like family deaths, and other things that make you physically ill or depressed. This can delay your ovulation, or make you not ovulate in a cycle. It will not affect you for long, and the next month you should come back and be normal again, anyway.
Just wanting to be pregnant stress as not only normal, it won't make any difference to our fertility! As Retro said, it is usually said by people who got pregnant whilst not actively trying or who got upduffed first cycle (they are the worst!)
