I have one son who is 7.5, a step-daughter that is 1.5 and I am 6weeks and 3 days according to my lmp. I haven't seen the OB yet, but did go to my regular doctor. We are really excited and I wish you all good luck.
BTW, with my first pregnancy, I though I had bad alergies, come to find out it's a symptom of pregnancy! Yuk!
