Sore ribs & tailbone?

Ashley • 30. Married for 8 years to my soulmate. Momma to Jack, born on 11.30.16 and Connor born on 3.16.19
Anyone else feeling this? It seems like my ribs are sore from sleeping on my side, but I obviously can't sleep on my back so I'm not sure what to do because both sides are sore. And my tailbone feels like I bruised it. Moms who have been pregnant before.. is this just usual third trimester aches? I'm 35+2.
