Well ladies, you gave me 100% girl guesses and you were 100% RIGHT!!!! It's a girl!!! I am in complete shock but so unbelievably happy!! Didn't get a print out of the potty shot (they don't provide those in many provinces in Canada unless you get a private scan), but the tech was experienced, felt confident in her answer, and showed me the three white lines several times. Between this baby's textbook nub and those clear white lines, I have no doubt it's a little girl. I just want to THANK YOU ALL so very much for being so skilled in the nub theory, and for being so incredibly supportive. I didn't do a great sway, but hopefully this will give others hope that it really is possible to have a girl after multiple boys, and that dreams really do come true!!!!
