Pink discharge, brown discharge, nothing!

So, I am due on my period tomorrow and on Saturday (4 days before period), I had one episode of very light dusty pink discharge in my underwear.

The next day (3 days before period), I had one episode of brown discharge in my underwear.

Yesterday, (2 days before period) I had pretty strong cramps that made me feel like there was no way in hell I wasn't about to come on. I even put in a pad as I thought it would just arrive.

Today, 1 day before period....nothing. Just a headache.

anybody experience the same?? I know it's only 1 day to wait but I feel like I'm walking on eggshells within my own mind and body- like if I get up too quickly or sneeze I might end up coming on. I know that sounds silly!!
