How did they manage not knowing?

Today has been a pretty emotional day. I have several friends that are pregnant too. Of the group of eight I am the latest due date. This has been pretty cool so far since one by one they all started wearing maternity clothes and really showing and I knew I would soon be there too. But now, I am not having that much fun being last. All of them have found out what they are having. Those who know me, know I am not good at waiting. I hate cliffhangers and stay tuned fors. Frankly I think that when a woman gets pregnant her belly should turn either pink or blue, or instead of that dark line on our bellies we should get either a star for a boy or a heart for a girl. I don't understand how our foremothers managed the whole pregnancy not knowing what they were having. I can understand that some women live for suprises and choose not to know even in today's technological world, but at least they have the choice. In our group of eight, the two that have girls already are having boys and the other five that have boys already are having girls. How perfect is that? Here is my theory... they have used up all the opposite gender wishes coming true and I will have another boy. I just know I will be the odd duck. In my emotional state today I even had a ten minute sob fest when the last one told me she too is having a girl. Her husband is very disappointed. He had proclaimed that there would be no girls in their house. She is kind of happy, but wished for a boy to help keep the peace. This really set me off. I went down the path of how dare they have my girl when they want the boy I know I am carrying? I know selfish, but not any more than the man whose reaction is I guess I have to make do with what God gave me, even if it is a girl. Don't get me wrong, I will love my son as much as I love the son I already have. I will be wholeheartedly devoted to him and all that his life will bring to ours. If only I knew for sure. I hate the not knowing. At least if I knew I could focus my energies and thoughts onto one gender. Instead I dream of girly things and then feel guilty that I am not dreaming of another batch of blue. I know there is not a darn thing I can do but wait... I just don't like it!!
