sleeping problems

Hi, I'm currently 37 weeks and 4 days, but I've been having a lot of issues with trying to sleep for the past couple of weeks, I've spoken to the midwife about it and she said it's normal, the little one is constantly on the move when I lay down and sometimes I feel nauseous when laying down, has anyone else experienced this or got any tips that could help? (having a boy if that helps at all)
