Exercises while pregnant

This is my first time pregnancy and my goal is to only gain 30lbs to the max and I hope I keep it up. I always enjoyed working out. I've been keeping up with my yoga twice a week but I'm not quite sure what exercises I can do througho pregnancy. Right now I'm 10 weeks, what can I do? I enjoy running, crunches, leg ups, squats, lunges, weights etc., I don't wanna do anything that obviously will be bad so what else can I do to help my body tone up throughout pregnancy? Booty workout, legs, arms & abs workout, please share! Thanks!
