Today's my 28th birthday?

Um, I'm 33 and I'm 10wks preg with my first. I'm trying really hard not to roll my eyes at you right now. You are fine. You have plenty of good years left. The stress and worry could actually be keeping you from conceiving. Take a break for a month or two. Don't use protection, but don't "try" either. I bet once you relax you will get preg.
