Aslong as your eating right and the dr says the baby is weighting and measuring how he/she is suppose to its fine :) don't stress about it to much just take ur vitamins and eat how ur suppose to eat... :)
Oh, and I haven't tried to lose weight by the way...I had shocking morning sickness for about 4 months so I couldn't eat much...my appetite is back now, so I dare say I'll start putting on weight again :)
I'm the same...I'm due December 11th and I've lost 3 1/2 kilos throughout my pregnancy so far (I'm from Australia, I don't know what that is in pounds lol)...my bub is measuring bigger than what she's supposed to (3cms or something) and shes healthy... so I'm all baby-belly, which I actually really like, it's cute :) just keep taking your vitamins, I'm sure everything is fine, just cos you're pregnant doesn't mean that you have to put on a crapload of weight :)
I was that way up until this past month ... I was losing from all day sickness it seemed as soon as I ate I would vomit it back up. This past month I've been nauseous but have gotten sick I'm due Dec 14 and have gained 6 pounds so far... As long as your doctor isn't concerned it should be fine I get a ultrasound every visit so each month my baby girl is measuring a little bit bigger than she is suppose to as long as you baby is on track you should be fine! Keep taking your baby vitamins :)
