Usually the baby is moving non stop. But yesterday my stomach was hurting constantly and hard to move around. Then today the baby I didn't notice moving much. I just felt her a few minutes ago and she didn't seem as active. Because when she usually moves you can definitely feel her. She's strong. Plus my stomach was hurting most the day today. I'm 28 weeks today, wondering if something could be wrong
