Im finally pregnant!!

Im finally pregnant and i'n terrified! I'm about 5"4 and I weigh about 270. I tried for years to get pregnant when I went to the Dr. turns out I had an ovarain cycst and it weighed 40lbs! I had it removed and I lost a few pounds. I was so excited! Now my problem was fixed, so I thought. Now 8months later im 4-6weeks pregnant. Although i'm excited and happy i'm also very very scared of having a miscarriage. My husband told me not to work so we could eliminate stress. But my weight scares me. Is there enough room for the baby to grow? What will happen to me?? I know i'm gonna get fatter. I just want to know what to do is there anything I can do to make sure I carry this baby full term???? Can I exercise? Please help me

You should be on prenatal vitamins. You should not try to lose weight but you can control your weight gain by discussing this with your OB.
Regarding exercise, if you have not exercised before you were pregnant, do not take up any vigorous exercise now.
In general, according to the American College of Obstetrics and Gynecology (ACOG) Committee Opinion:  30 minutes or more of moderate exercise a day (like walking) in absence of any medical or obstetrical complications should recommended for pregnant women.
"Previously inactive women and those with medical or obstetrical complications should be evaluated before recommendations for physical activity during pregnancy are made."

Therefore, the bottom line is that you must discuss this with your obstetrician.
