Losing Sleep...help!

Hi everyone this is so new to me. My first child. I never had any problems about sleeping once my heads hits the pillow day or night I am knocked out.

But for my second one I am having a hard time sleeping. Whether its at night or during the days. And most especially the days I work a 12hrs night shift. So I need to rest during the day. I’ll probably sleep 30mins to an hour then thats it. Any sounds or movements at home I am up! Then my morning sickness kicks in. Headache and nausea...😫
