Best body pillow

Michelle
I am 7 weeks, 2 days and am having lower back pain. I've been researching different body pillows, but they're all so confusing. I've read that the top seam on the u-pillow is hard and uncomfortable. I'm stuck between the u and the c shaped pillow. I'm 6 feet tall, which is something that needs to be taken into consideration....help! Lol
