I need help

I'm 14 weeks 5 days pregnant and what little sleep I get is Fu****g precious to me right now. I'm working and up at 6am every morning Monday to Friday and not home untill 5pm. It's exhausting. The problem is my partners sleep clock is different to mind as in I sleep when I need to sleep and he sees sleep as a defeat and waste of precious time ( it'll be good once baby arrives but not right now when I'm exhausted)

The smallest movement wakes me up, him coughing in bed, last night he leaned over me and basically squished me to put my phone down beside me so I could hear my alarm this morning which I know was him trying to be nice and all but it would have taken two seconds to get up and do it instead of squishing me and waking me up to do it. The problem is once I'm up im up. I've never been a good sleeper and prior to being pregnant was on sleeping tablets from the doctors to actually stay asleep.

Is all hope lost? Will I smother my poor partner? Will I move out into the livingroom? Find out next week on snog, marry avoid.

No seriously I need advice.
