Ive owned my body pillow since i was 9years old, i am now 21 years old and 21weeks pregnant and still have the same body pillow that ive had since i was 9 and i thank god i kept it for this long because it has came in handy now that i am pregnant. A plain old body pillow works just the same as those expensive pregnancy boppy pillows. I highly suggest getting one. :)
I would suggest getting one or at least a body pillow. The farther along you get the harder it is to get comfy laying down. Having a pillow to support your body and mostly you ever growing belly is going to help a lot
