Lovely scan pic Lozza!
Happy, know what you mean (12+1 here too). No backdoor vomiting incidents (poor you, bet that was nice to clean up...), but still queasy, especially if I don't sleep during the day, and my boobs have just started hurting! It's like they've decided to grow now I've had my scan and I've decided I can be properly pregnant!
Dusty sorry you're feeling poorly too, food poisoning is the pits. Don't worry about the twins though, they'll be fine, just make sure you're keeping your fluids up.
Cloey It does sound a little strange to lose 5 kg (I think in Metric so I know exactly what you mean!) if you haven't been ill. I only lost 2 when pregnant with DS and it's been 1 up 1 down this time. Both pregnancies have seen me go from hearty meals and snacks to just snacks and half meals - last night was a packet of Hula Hoops and some Orangina, thanks to scan excitement stopping me from sleeping properly! Perhaps mention it at your next appointment? Have you ever had any thyroid issues?
But then again, as everyone else has said, different scales plus a loss of a couple of kilos for baby growing (and different clothing) could add up to 5. Have you tried the same scales you weighed in at 80 on yet?
