tender abdomen?

Hello ladies.
Just wondering if this is happening to anyone else?
I'm currently 17.3 weeks and my lower abdomen is feeling super sensitive. When hubby passes his hand over it it feels massive and feels a little sore. FTM here so I'm not sure if this Is normal or not. I'm assuming it's because everything is stretching down there? I've also been feeling her poke me every once in a while usually after a meal.
