Weight gain first trimester

I'm reading how 98% of everyone on this site has lost or had not gained any weight in their first trimester.  I've been nauseas and exausted and have not gone to work out or move for the 2nd month since I've been sick and exausted.  I did however eat carbs since it was the only thing that lessened the nausea.  I'm 14 weeks now and have gained 12 lbs.  I'm noticeably prego and everything has become bigger.  I don't look like the athletic type I was 14 weeks ago. Has anyone else gained weight ?
