No, but get yourself a grabber (reach tool) anyway because straining your ab muscles can cause problems for YOU (which won't affect the pregnancy). These things are amazing! I love them for pregnancy because I get SPD and cannot reach the floor so easily even now at 18 weeks. I use mine to reach things high and low, as we store things up to the top of our 9-foot ceilings in the laundry room and at the top of our 9-stairs linen closet (medications and things we don't want the kids to get into!).
I bought the Ettore 49036 Grip'n Grab Reach Tool, 32-Inch on Amazon for 17 bucks, and if the kids don't get their hands on it (I'm on my fourth.....), it will last and lifts up to 5 lbs.
