I'm 23 weeks pregnant with my 4th baby however my youngest is 9 next week so there has been a gap between pregnancy's also I have 3 boys and found out I'm now having a baby girl. My worry is that I'm constantly hungry! I was never so hungry in my other pregnancy's, from what I can remember, and I'm just worried as I was never the slimmest girl before. It's not just wanting the odd snack I am hungry every waking minute. I can never get full. This started last week and I was just wondering if anybody else I'd feeling like this.
