Pregnant..... again, now an important question!

oy, 1st trimester dumb-dumbs---to lose weight, I was eating 1600-1700 calories per day. Now that I'm preggers and hungry, I'm still exercising 5-7 days a week (switched to 8 pound weights instead of 15-16 pound dumbbells and doing cardio for 30 minutes a day)..... is it okay that I upped my calories for the day to 2000? I only want to gain 15-25 pounds while pregnant..... I am 5'6 and 215 pounds....
