How to manage early labor contractions?

I’m a FTM and started having irregular contractions last night (around 28 hours now). Some are mild and some are super intense where I can’t even talk through them. They’re mostly 45 mins apart now. Anyone have any tips on how to get through these until it’s time to go to the hospital? Like certain positions or something? I know they’re going to get worse and much more frequent and I’m freaking out a little. 😰
