Energy drinks while pregnant?

Are any energy drinks okay while pregnant? I currently have a toddler, a 6 month old, and I’m 7 weeks pregnant with #3. I found out 2 weeks ago but had been drinking an energy drink a day up until the point I found out that I was pregnant. I never drank them before but since having my second baby I’m constantly tired from being so busy. I’m REALLY struggling with my energy levels. I was already a pretty tired person from being a full time single mom but now this pregnancy is making it worse. I can barely hold my eyes open during the day and all I want to do is sleep but I can’t because my kids never nap at the same time. I’ve tried drinking coffee and it doesn’t do anything, energy drinks were the only thing that actually helped me get through the day without being overly exhausted but can I drink them while pregnant?😅
