Hi,

I'm almost 23 weeks and havent really gained anything, maybe 2 or so kilos if anything....

I had gained ALOT more at thsi same stage wiht my first... I had gained about 15 or so...

With my second I had gained about 4 or so by this point and I gained about 10-14 all up (though I lost alot at the begining)

I dont worry too much, they dont weigh you anymore as apparently its not that big a deal... it is important to eat when you are hungry as someone else said and make sure you drink plenty of water too
