Discharge... middle of the night

My SO and I did the deed last night. He came in me and I’m due for my period. I was hoping it would make me start because most of the time it starts me period. Anyways, I woke up in the middle of the night feeling wet. I jumped right up because I thought I started my period. I have a whole bunch of clear sticky discharge everywhere. What the heck is this?? It wasn’t his cum bc of the consistency and color.
