I totally agree with you! I was lying in bed early this morning thinking the same thing! I am in the same boat as you. We have been TTCing for the last 10 months. I really thought about the laughing thing last night as I was visiting with a gf of mine last night (as she readily comes over once a week for a few drinks--which of course I don't indulge in anymore) and we were talking and laughing! It made me feel so much better. That is definitely one very important thing with TTCing is to relax, have fun, and laugh. My husband and I are a couple of comedians when we really get going! I try to remember that it is important to enjoy yourself. I hope you get your Big Fat Positive!
I'm convinced I could market this idea to someone! haha. On a more serious note, I believe those of us who have been ttc for some time fall into the pit of losing the joy. I know I do. We build up to the 2ww, and then suffer great disappointment when it just doesn't happen. Let's all try to find a little humor every day. A happy woman is a happy womb for a baby. (I say this as I head to take yet another opk, check my tracker, and analyze my AF's for the past nine months. lol)
