Help please!!!

Hanna
My period should come October 2nd should I test now or wait till the day of? 
I've been ttc with my SO for over a year now & don't want to be disappointed.
A little TMI but I want to know if you guys get the same feeling when your about to start your period....
It feels like something is trying to leak out of your vagina but doesn't? Idk its kind of hard to explain...
Please help
