Low uterus

This may be tmi, but I'm worried. I was very constipated this morning. Jumped in the shower after and felt my uterus super low and hard, (not anywhere near my abdomen). I'm 14 and a half weeks. Should I be concerned? No pain, other than stretching in my groin area. Did my pushing do any harm?! My husband says I haven't been showing yet, just my belly fat sticking out further, maybe due to bloating, meaning, no hardness in my abdominal area just yet.
