First Pregnancy Bloat?

I've seen all of the posts about "showing" early, but I feel like they have all been from second or more pregnancies. I am just over 8 weeks and already having discomfort with my pants (and definatly bras) and starting to look a bit round already. I've gained no weight so I know it isn't fat or from eating too much. Just wondering if anyone else is in the same boat. Everyone is telling me it's too early....but here it is 😂 would love to know I'm not alone.
