So I'm a first time mom, this is the 2nd time I've been pregnant but the first pregnancy ended in a miscarriage at 12 weeks so I've never made it this far. I'm 16+4 weeks and my stomach down lower is kind of tender. More on the left than the right but still tender. Yesterday I felt constipated and gassy (TMI I know) and I still haven't been able to go to the bathroom. I just want to make sure I'm just feeling more intense constipation and not something more serious. Its happened before but not as intense I guess. It's only tender when I sit too hard or push a little on my belly. Is this normal?
