Struggling to sleep!

Jodie • Mummy to missus Miya Isobel. Born teeny tiny at 36 weeks! ❤️
I'm currently 8+4 and some would say I'm having the best pregnancy, no morning sickness or tummy troubles. My biggest problem is I cannot sleep, no matter how tired I am. I work 12 hours 5 days a week so I should be dead on my feet but It's just not happening for me. Anyone else feeling the same?
