I have a quick question about third trimester weight gain. I was about 8st to begin with and am now 33 weeks, and have put on just under a stone. I have read/heard to expect a weight gain of about 1lb a week in this trimester but don't seem to be gaining anything like that! Should I be worried? I am eating healthily, never let myself go hungry, but wouldn't say I'm eating necessarily a lot more than usual. Is this OK? Thanks!!
