Plus size pregnancies

I'm a bit disappointed. Yesterday was my first midwife appointment (!) at 10 weeks. The midwife was super nice, however, at the end of the appointment she told me I would have to see an obesity consultant for the remaineder of the pregnancy due to my weight. I understand they're being cautious. However, this still makes me sad. I'm a size 18 US/ 22 Uk  and didn't think I was that huge. 
What I'm looking for is other plus sized ladies pregnancy stories. I'm positive that I can have a happy and healthy pregnancy, but I'm just looking for reassurance.
