big, big day

Tomorrow is my 18-week appointment with the OB-GYN. That's at 1:00PM. Then, at 3:00, I am scheduled for an anatomy scan with the specialist-guy in Beechwood. This should tell us if we are having a Colin or an Audrey. I'm so excited I really don't know what to write, but I guess it would be appropriate to record my gender thoughts before the scan.
Right now, I think I am carrying a boy. This is mainly because of the old wives' tales, ie, I am craving salty things, my left breast is not noticably bigger than my right, my pee is day-glo in color, etc. But, the problem is that I've checked several wives' tales sources, and some of them contradict, one saying the signs indicate girl and another saying the same signs indicate boy. So, I am basing my guess on the first source (so scientific) I consulted. The one thing I did not do was swing a pendant over my belly. That is probably the key predictor; I've just been lazy.
Last week, I was talking to my mom, and she asked of I had the "brown line" under my belly button. I checked, and I don't. Not even a trace. Now, this is a big deal in my family. For my mother's people (those being my aunt and two female cousins), this is a huge pregnancy symptom - the line is really dark and manifests itself pretty early. In fact, as my mother recalls it, she didn't know she was pregnant until her sister pointed out the line (linea negra). Well, my mom, aunt, and two cousins, each with their pronounced lineas, all had girls. Another tick in the Colin column, perhaps.
I think I'm more comfortable parenting a girl just because of my girl-life experience; I think I'm better-suited to parent a boy because of those same, girl experiences. I feel like I carry too much baggage to raise a healthy, happy girl, and I am scared to death of the mental/emotional damage I might cause a young woman simply because I have such trouble with my own body image and its relative importance in my life. I know that my relationship with my own mother is complex, on good days, and totally *ucked, on others. I just feel like I could hide my junk better from a son.
Well, Mr. R has been quiet on the subject of gender preference. Based on his interaction with his niece and nephew, his mother says he's partial to girls, but she's generally wrong about all things Mr. R, so go figure. Though he hasn't said it, I think he is concerned about my girl-raising abilities, too.
What we do know is we are one-and-out, so maybe we both hold back our preferences knowing our odds are 50/50, and - like everybody else - default to the "I-just-hope-it's-healthy" retort.
Today, I think I will enjoy my last day of ignorance (at least on this subject).
