weeing in my sleep problem or not?

So basically.. I never had problems when I was little when it came to wetting myself or wetting the bed, I've always been great ever since I came out of nappies until now I go to the toilet before I sleep. I haven't slept deep properly for months, and I don't know if it's the problem. But I've woke up twice now on my belly weeing myself..the first time I was lucky to stop it as I. Old enough to know like anyone is. But the second time I peed a lot more and it was actually on my bed... I'm having problems at the moment my boyfriends a total idiot. I just don't know what to do, I've never had children I'm 16 so I'm young. PLEASE HELP
