I think I was probably up by 8-10 at the end but I'm only 5' feet tall (I had an appointment near the end of my 1st trimester but not quite at the end). I don't own a scale and have been trying not to stress about it too much. I had a lot of nausea for a bit and eating made it better but it was also hard to force myself to eat.
I feel like I've loaded up on carbs and I know I'm just starting to show but I also feel like I probably put on a few more pounds in the last 2 weeks (15+3 currently). My nausea went away around week 9 but the last 2 days it's been very present unfortunately.
It's such an individual thing, and like azure says, trust your body knows what it's doing. Don't stress too much about comparing yourself to others.
