I have a friend who was infertile. Back before I knew her, around the time we were thinking of trying for M, she did a cycle of IVF. It failed.
Six weeks later, she called her RE. Her period was late, she felt like crap, and she wanted to know what the heck was going on. She just wanted to be able to move onto the next cycle. He told her to take a pregnancy test.
The way my friend tells it, she cursed him out five ways to Sunday, told him to stop playing with her head, of course she wasn't pregnant, and why was he doing this to her? But he insisted, she tested, and her daughter (one of the coolest, funniest little kids I know) was born 7.5 months later.
Is it any wonder why, faced with this incredibly tangible proof that it happens sometimes, that I am secretly hoping that we'll somehow get knocked up this month? Of course, my friend was full of completely functional parts that just hadn't happened to be functioning, whereas I am not only missing at least one part, but key others appear nonfunctional at this point. But no matter. If it happened to her, dammit, it can happen to me!
Ahh, delusionville. It's such a nice place to live.
