17 Weeks Tight pinching?

Ann

I'm 17wk6d and have been experiencing a tight pinching on my left and right side of lower abdomen. I'm thinking it might be due to over exertion as my husband and I have been running around the past couple of days, cleaning, moving stuff, and prepping the house. Like I'm doing too much and my body is telling me to chill the @&$% out. Has this happened to anyone else? Don't want to be using too much energy and hurting the baby.
