Keeping things fresh while TTC?

Hi ladies! 
​So like most of us since me and hubby started TTC (16 long months ago) most of our sex life had focused on baby making, a few hiccups along the way with a roller coater year- we got married, lost my dad, bought our first house, almost lost my mum, his mum was diagnosed with breast cancer... The list is almost endless!
​Anyway, I'm worried that things have become a little samey with all the stress and thinking about baby making, how do you keep it all fresh and fun?  Any tips for getting that spark back?
​Don't get me wrong I love him to bits, and couldn't have survived everything without him, but it would be amazing to have that carefree feeling back 
​Thanks! x
