Gaining Weight

Never in a million years did I ever think that I would have to worry about not being able to gain weight. I mean that's every woman's dream right? Eat whatever you want and not gain an ounce. Normally I'd be over the moon excited about this recent development except I'm trying to grow a couple of babies. So far I have lost about 8lbs since finding out that I'm pregnant. I'm nearly out of my first trimester now and was hoping that by now I'd be seeing some weight gain. Again an other sentence I never thought I'd hear coming out of my mouth.
I will attribute this weight loss to morning sickness 100% I've been pretty sick the whole time we have known about this pregnancy. Which I guess is supposed to be normal and blah blah blah with twins. I did end up having to talk to Dr S about how bad it had become, which is when he put me on Zofran. I'm not a fan of being medicated and try to avoid it at all costs. So the Zofran is only taken when I'm having a really rough day.Beyond that I'm just trying to tough out the morning sickness like anyone else would. So I do blame my weight loss on the morning sickness and hope that it will start to subside soon.
Here is what makes me feel a little better about the weight loss in my first trimester. In all I'm supposed to put on close to 45 lbs with twins! Losing 8 lbs helps me feel just a little better about my final goal weight. This is such new territory to me. I've always been concerned about the opposite. I keep putting on weight I can't take it off, I want to lose 40lbs. And now its completely reversed and I'm having to worry about weight gain. Funny how that happens!

PS Once I have my next appointment and officially make it to Trimester Two then I think I might start doing weekly updates. What do ya'll think? Good or bad plan?
