Is night sweats an early sign of pregnancy?

April

I woke up drenched in my sweat during sleep. I only had 2 sheets on me. I worn tank top. The room is pretty cold but I sweated anyway. I normally sweat when I’m approaching my period but I’m due for my period today to Thursday and it was the first one that I only sweat once so far. Can it be early sign? I have no spotting or any type of bleeding yet. My cycle is always either 26-27.
