CANT STAY AWAKE.

Help. Has anyone else been like this..? Im 31 weeks, and I can’t seem to stay awake for anything. This started maybe 4 days ago, the past few days I’m having a hard time staying up, I get a full night rest and during the day I just pass out with out noticing. Obviously I’m sitting, never when I’m standing up. I have an almost 2 year old and this is so dangerous because while we are in the living room my eyes drift off and my head nods and I hate that I have to keep her in the playpen because I can’t keep my self up. It’s so dangerous to me and the fact I’m not doing anything with her. I tried cold shower, black coffee. I’ve also been seeing black spots recently. I do have gestational diabetes but I’m on medication for that. I had low iron with my first and got medication but this is nothing compared. It’s worse. My husband is marine so he’s always at work and has to wake up early, not the mention he really isn’t helping that much at home. This Is to stressful for me right now.
