Insomnia- Early Pregnancy Sign?

Hey guys👋🏼 So today I am 7 DPO, which I tested and didn’t get a clear bfp. Which I know it’s early on so I’m going to test again in a few days. But, I was wondering if anyone else had insomnia being one of their first pregnancy signs? For the last 4 days I have been waking up early between the hours of 3-5am and tonight for example, I’ve been up since 1 am & don’t have my alarms for work going off until 5am. I have energy throughout the day, but have yet to have a full night of sleep recently. I just wasn’t sure if others had this happen to them & they ended up pregnant? Thanks!💘
