top of uterus hurts?

Caroline
Hey ladies! So I'm 27+3 today and for the last two days, the top of my uterus has been hurting. Just a small spot that feels tight or like its cramped. It hurts when I bend and or move from side to side. I know it's not Braxton Hicks because I know what those feel like and have had those before. Should I be concerned? Or is this just me continuing to grow and feeling some growing pains? Thoughts?
