Yes, this is actually pretty common in the second trimester, the digestive system slows down during pregnancy and that can cause a lot of bloating and gas even after the nausea settles. It is good that you are past the worst of the morning sickness, but since you mentioned you cannot eat much, it might be worth mentioning it to your gynae or PD at your next visit just to make sure everything is on track. Try eating smaller meals more often and see if that helps a little in the meantime. You are doing great, hang in there!
