I am a little over 11 weeks pregnant with my second baby. Pregnancy Pillow advice?

I'm already experiencing back pain and some hip pain while sleeping and I am looking into a pregnancy pillow. With my daughter I used the boppy full body pregnancy pillow and within 2 or 3 months of sleeping on it, it flattened out like a pan cake and did nothing for me. I don't mind spending some money on a good pillow as long as it will last me the duration of the pregnancy! Any recommendations on a good pregnancy pillow because, ouch my aching back! Thanks!
