Wow, there is lots going on in here!
Dm - love that pic of you and your son right after he was born. So sweet!
Princess - have you been seen about your spotting? It might give you peace of mind that everything is ok.
mocha - I think 12 weeks is a good time for a nub shot! I don't really get nub theory but it is fun to guess anyways! Looking forward to seeing your pics.
z- good luck telling your boss! i know it can be stressful but I think they usually take it better than we think they will. It will be exciting to have a co-worker to go through pregnancy with - are you friends?
Have you guys seen this website? I thought it was really interesting as it shows the baby genitals at the different stages. It is surprising how they start out looking so similar!
