Just popped by from December board to wish you the best of luck for tomorrow! I know you are still hoping for a girl deep down but I can tell you, that you will be thrilled with that little baby when he/she comes no matter what the sex is.
I found out at 16 weeks and then confirmed at 20 weeks that I was having my fifth boy and yes I was disappointed at first but I am not any more, I think having time to get used to it helped but I am now so excited to meet my little boy I have come to terms with the fact I won't have a little girl now, I suppose it wasn't meant to be for whatever reason. This will be my last child too as we can't afford another one! also there's no way I could cope with six children! I do understand how you feel, but I just know when that baby comes it won't matter what the gender is, your heart will just melt to have him/her in your arms at last!!
I am so jealous by the way, I still have 8 weeks to go and I am sooo fed up with being pregnant now,lol
Best of luck, I will be watching your posts for an update, take care and hugs, Cal x x x xx
