It started with the coffee.  I decided to switch to decaf when we began trying, but I had to scale down to half-caf to stave off headaches. I talked to my OB-GYN about it, and he said not to worry, because just one cup was fine.  But elsewhere I was being told that caffeine could interfere with our efforts to conceive a baby.  How to know what was right?  I am still drinking half-caf, occasionally giving in to cravings for a second cup, and am constantly concerned that I’m preventing my chances of conceiving a child.
