You have a beautiful belly!  I'm jealous.  I'm 14 weeks and 4 days and at my last doctor's appointment we found the heartbeat quite low.  I still had baby belly left from Arianna, which is starting to get bigger, but it's not baby.  I don't have a nice firm belly like you probably do.  Does that make any sense to you? I'm not sure I understand why my belly is getting bigger, but not the way it should.  I've even lost weight and then only gained back what I lost.  My friend wants to "document" my pregnancy for her photography portfolio, but I'm still so self-conscious about my belly.  I have started wearing my maternity jeans, just because my normal jeans don't really fit anymore, but I'm so ready for the rest of my maternity clothes.  I loved the way my belly looked when I was pregnant the first time.  I'm just trying to be patient until the time when I can be proud of my belly.
I hope you don't mind me spewing my thoughts about this.  I haven't talked to anyone about it.
But you look fabulous!

I was about that big at 6 months with my first but just like you I popped straight out with the other one. I was about that big at about 3 months too...
