Period sleeping hacks

Ana
Okay so I just started my period and first two days I wake up a LOT at night to go to the bathroom cause I feel like it leaked everywhere, but of course it didn't. I even have a towel one bed just in case it does. I don't have very heavy period like I used to have, but I do have the worse cramps. 
Do any of you have any hacks for speeping postitons and how to feel comfortable while sleeping and not going to the bathroom every hour?
