I'm a 28 yr old female 5'4" 110 lbs &10 wks pregnant. Can I maintain my weight or should I be gaining extra weight in addition to the pregnancy?

"Weight a minute" Since you are pregnant there will be associated weight gain of between 22 and 25 lbs. total. However, it will matter more to your OB MD the RATE and which you gain the weight rather than the amount. Consult with your treating OB and don't miss any scheduled appointments. Congratulations and Good Luck!
