Maybe try to prop up your back with some pillows instead of lying flat on the bed. It gets more uncomfortable as your tummy grows bigger. You just need to find your comfort spot / position.
Get your partner to press / massage your back while you lie on one of your sides, it helps a lot for me. Elevate your legs as well few times in a day. Put a pillow in between your legs when you’re lying on your side.
Trust me it will get so much more uncomfortable in 8th/9th month of pregnancy. Your tummy will be heavy and no matter how you turn, it will be uncomfortable because your back will ache like hell. So better find a position most comfortable and try switching positions every few hrs.
Another brilliant idea is to go for chiropractic, it is expensive but worth it.
Avoid drinking a lot few hrs towards bedtime so you don’t have to get up and pee every now and then. Drink more during day time instead. I know even a cup of water just before bedtime can make you get up many times in the middle of the night. So best is to avoid drinking a whole cup. Substitute your water intake during the day instead.
