You might be infertile if....
...You've had dye and/or saline injected into your uterus.
....Your husband actually knows what EWCM stands for and asks if you have any.
.....Your husband and the sterile cup have become good friends.
...Your preferred method of sperm/embryo delivery is a catheter through your cervix.
....You've had more than 3 appts a week with the love wand. Actually, you might be infertile if using the phrase "love wand" in conversation is normal, and you are not referring to anything resembling "The Rabbit".
....You get excited over the size of your eggs, and better yet....if there is more than one!
.....You actually get excited over injections, and think the Follistim (or Gonal-F) pen is one kickass tool.
....Anyone at the RE's office knows you by name.
So, what do you think? Ring a bell? ;-) Feel free to add your own in the comments section! =D
