You are 27 weeks and have lost 10lbs since your first OB appointment you have been eating lots has this happend to anyone what could cause this?

yes i lost over 2st when i was pregnant, it could be caused by many things such as morning sickness, a hormonal imbalance, or an over active thyroid as long as you and the baby are well and it is developing correctly there should be no problems and should corect themselves after the birth. When I was pregnant I had a bad tooth ache and cut out the sugar and lost weight. My doctor had broght it to my attention because I didn't realize I was losing weight. Everything was fine and my baby was born healthy.
