Bachelorette Party and Second Guessing

This past Saturday was my Bachelorette Party. My sorors and friends did a great job putting it on and I appreciate everything they did. I made the announcement that I was pregnant before everyone did their third shot. (Wish I could have done one). Most people knew but a few were surprised. On top of that, no one wanted to believe that I was 18 weeks, which is approximately 4.5 months. One of my sorors told me she was huge when she was 4 months. So that makes me ask a couple of questions.

• Is it because I'm skinny that I don't show as quickly as others?
• Should I be eating more? (Even though I swear I've been eating like a pig)
• When am I finally pop out with the big bump?

It really worries me and makes me feel like I'm not doing something right when someone else compares their situation, but I guess that's why every source I read says that different women develop differently. My next appointment will tell me if the baby is healthy and if I need to eat more. I weigh myself about every other day and I think I'm doing a decent job of gaining weight, but maybe I'll try to pack on more pounds after the wedding.
