Anybody else get lower belly pain?

Been having some seemingly muscular but sometime harder to tell pains in my lower belly, across from hip to hip under the bump and slightly higher. Not all the time, and not so painful it affects much, but sometimes makes it harder to bend down, and more uncomfortable. I figure it could be gas? Or maybe my muscles are just tired? (I haven’t changed much about my relatively active lifestyle. I don’t work out much but I’m constantly on my feet). Seeing my OB this week and will absolutely discuss with her, but wondering if this is something others experience or if I should worry. I still feel the baby moving lots, and kicking. Hard not to worry though. Thanks in advance!
