I'm 5'5 ...(btw, that's not really tall at all!)but i'm also very athletic. I was a skateboarding chick

My abs were def tighter

Now i'm just very on the go! Makes me still feel like a lardo being 145lbs!
105-110..you girls are all skin and bones,lol!! Ya, you're more apt to show when you're thinner,but 1st pg's you usually show later.
When I was pg with my 1st, I didn't get the "bloat" til about 5 1/2 months! I hid it from work that long, and no one knew or really believed me! I still didn't even really pop to the point where people could notice my bump until about 7 1/2 months!!!
I wouldn't worry about the bump not showing right now...it will

then it will be so uncomfortable you just wish the baby were out already!
This pg, my "bloat" came sooner..about 6-8 weeks. My abs just aren't as tight as they used to be before my 1st, so i'm sure as being second pg too, that's why i'm showing alot sooner. I don't really have the bump in the morning either, it's weird! Only when I eat does it seem to fill up and show my baby bump! I am still able to hide it a bit at work, although they already know this time. It actually seems like in the past week or so it's gotten a bit smaller :/ I'm sure it's just more fluid disappearing. Just scheduled my first prenatal appt for next week, so it'll be brought up, and i'll be checked out.Not worried...excited!!
you should be too!! congrats, and good luck!
