I'm currently pregnant with #3 and we are not finding out. I had sore bb's with my son who's 3 and DID NOT have sore bb's with my daughter (she's 2). So far, I have not experienced sore bb's with this one either, which is definately a girlie sign for me.
We are not finding out the gender, but so far, I've had morning sickness (only threw up a few times, but bad dry heeving all day), my face is breaking out still (20 weeks) and I never get pimples. Not sure how I'm showing yet as my bump is not that big - some days it looks low and some days it looks high.
Good luck on your girl! When will you find out?
