HELP!

I can't sleep at night.. Like literally no sleep until its like 9am in the morning. It's been like this for the past 3 days😩 I've tried going to bed at the same time everynight and all I do is toss and turn, also tried drinking hot chocolate 2h before bed and basically everything to make you sleepy. But here I am 5am in the morning and still wide awake. What's wrong with me!? I'm 26 weeks pregnant, but I don't have any problems laying down or getting comfortable. Its just that even when I'm sleepy I still can't sleep!? UGHHH this is so frustrating!! Any suggestions you guys!? My last resort would be taking benadrly, I'm not so fond of medication that aren't really necessary to take..😪😩😭
