I know it's not good to worry and stress, but I just can't help it at this point. My husbands in the Air Force and we're currently stationed in Japan. I'm about 8 weeks pregnant with my first, at 20 yrs old. Anyways, we're moving to Alaska around November. By then I'll be around 25/26 weeks. I weighed about 90 lbs before pregnancy and have lost 3 lbs so far, and being so underweight I'm worried I'll go into preterm labor during our big move. This is 15+ hours of flying. I haven't seen a doctor yet besides blood tests and paperwork. They won't let me schedule my dating ultrasound until I'm 12 weeks. So I'm stuck worrying about everything until they can get me into an appointment. Anyone have a preemie before? What gestational age? I'm so nervous about this.
