Nazly, nothing of mine fits either. You are about the same as me (similar number of weeks too). So if you are huge than so am I. I already have resorted to wearing some of DH's clothes where I can rather than spending money on new ones.
The worst bit was having to buy new pants as my arse has expanded so much and mine were ridiculously tight and uncomfortable, though I think its just my hips - they increased in size by 3 inches before I was 10weeks and I put on any weight at all. This makes me really unhappy, as I suspect that even if I loose all the weight, I'll never fit back into my skinny jeans again.
I won't even go into how much my boobs have expanded. I was a ridiculous size before and well, enough is enough already.
Last night I made the mistake of going for a bath. Getting in and out was difficult as bump got in the way. I don't see how I am going to manage it on my own in just a few weeks time at this rate.
However my biggest problem is that if I get in my car, my bump is already touching the steering wheel. I'm ok in DH's car, but I hate driving it, as its so big. Fortunately, I don't need to drive much at the moment, but its depressing and something I hadn't expected to happen quite so soon. I guess the plus side is it stops me shopping or bumping into people in shops passing comment about my size!
I think if you are short, or petite you are more likely to have a bigger bump to body ratio going on. I still feel ridiculous though.
