hi,
I'm only 21+1 today, but I find that all my maternity tops have suddenly got too short to cover my bump properly. I had a few tops which fit lovely even two weeks ago, now I have a constantly naked lower half of my bump and it's bloody cold!
funnily enough, the tops that do still fit me nicely are all non-maternity primark, they just seem to stretch, but all my dorothy perkins, gap, H&M and next tops just leave this big gaping opening :(
It doesn't even matter whether they are a size 6 or a 10, the 6s actually fit better everywhere else.
Half of my maternity jeans have started feeling too tight around the bump bit as well, and the other half have started sliding downwards when I walk. (little story here: When I was pg with DS, I once had an entire conversation with my BIL, then turned around to find that half of my lady garden had been exposed because my trousers had made their way down without me feeling it. 
but that was at around 35 weeks!)
does anyone else have this problem? I know it's not exactly earth shattering, but considering I've been constantly ill for the past 6 weeks with various infections, I don't fancy getting anything else.. or exposing my netherregions.....
