Sleeping anxiety

So I’m 25 weeks with baby number 4. I dont remember being so anxious about this with the other pregnancies. So I know left side is best and I try to do that but I get to sore on the left side and my arm falls asleep so I have to turn over onto my right side. I try to not stay there for a while but sometimes I fall asleep and wake up an hour or two later still on my right side. Just wondering if I’m worried too much about it and if it will actually hurt baby if I do sleep on my right side sometimes. I’m never on my back so that isn’t an issue for me. Thanks in advance
