Showing already???

I'm nine weeks then, my first pregnancy. I haven't had any morning sickness at all, however I have been really hungry and extremely exhausted.... Which makes for a terrible combination. I walk every day but I haven't run for months. I think I've gained five lbs 😭😭😭. So I'm not sure if this new "swelling" is the baby or my newly found crappy habits. I know it's ridiculous and verging on vain to be thinking this way, especially with this amazing little blessing. But I feel gigantic lol and it's early! Anyone else feel similar?
