Tummy sleeper.

I am 8 weeks and I am a stomach sleeper. I was told sleeping on your stomach is fine because the baby is still small but it's becoming uncomfortable. Sleeping on my side doesn't work, I end up waking up with a sore body. And sleeping on my back gives me bad headaches. I'm so uncomfortable but so tired!!!! 😫 Anyone else having this issue? What do you do for comfort?
