What should i do?!

So im constantly asleep during the day no matter how much i fight it! Which causes me to be up all night, which people hate it but i cant help it ive tried everything i could think of. At (night) i usually go to sllep at about 4am them we are up at 6:45am then i go back to sleep at approximately 8:15 or 8:30 then dont wake up tell sometimes good couple hours 1pm then up for about two hours then asleep tell 5:30 them im up for rest of night. Well i have a baby appointment which takes me about 33 minutes to get there today at 12:30. Its currently 1:25am for me i have to be at that appointment which im going alone. So what helps u guys during first trimester. This is everyday since day 1 of pregnancy and its just increased over time. Ive tried staying awake during day like getting cold drinks but nope. And i have tried getting comfy which i am when laying down!? Any help i will try anything at this point!
