Big and pregnant

Warning! Rant ahead!

I'm secretly (not a secret anymore!) hoping that I'm having twins, simply for the justification I would receive with my already pregnant appearance. With Morgan I was wearing my regular pants until I was in my 7th month. I even had a size 5 pair of pants that I wore to work all the time when I was very pregnant! I never fit back into those... :( This time around, my much larger sized pants are already getting very tight, my shirts make me look like a stuffed sausage, and I'm only 2 months preggers. Now, I know that your 2nd pregnancy and on you will show sooner than your first, do to stretched ligaments and such, but this much?!
Today I flipped through a photo album that had side pictures of pregnant me. They were spaced about a month apart and were meant to illustrate how much my tummy grew each month. At 9 weeks I look about the same size as I did when I was 4 1/2 pregnant with Morgan.
So what do you do? Lay off the food? Nope! That would make me oh so sick. Eat healthier? Eh. I don't think I'm doing awful. Like last time, my sweet tooth nearly vanished and I rarely eat sugary things. I'm big in to fruits and veggies. (And Toquito's.) Exercise more? Here I must admit that I have taken a break from the aerobic class that I'd been attending. Last time I went it made me extra nauseous, and I just don't have any energy. (I do plan on attending once the morning sickness fades though) Also, I refuse to break out the packed away maternity clothes yet. Too soon! They would only serve to make me look even farther along than I do already. So the way I see it, my only option is to silently hope for twins. I'll deal with the double crying and feeding and birthing later. For now I just want an excuse for my pre-mature abdomen engorgement.
