Pregnancy pillow help!

Hello ladies. I am 16w2d along with my healthy baby boy 💙 I have struggled with insomnia my entire life. It's awful. I take melatonin before bed and it's seems to help a little bit. But I am worried about my sleep when I get further along. I already get extreamly uncomfortable when laying in bed and end up tossing and turning for hours before finally falling asleep. I sleep on either my back or side. I found that putting a pillow between my legs when laying on my side, helps make me more comfy. I was hoping that you ladies would be able to tell me if the pregnancy pillows helped with you or not? Is it worth giving it a try? Also, do you have any brand or style recommendations? Thanks abunch mamas 💖💙❤️
