Have you had this the day before your missed period?

Okay so I know this is a bit gross: and I looked it up and so far I found it is normal...but I am checking. I have had this liquid discharge along with creamy white. The liquid is also white. I got a few drops actually on my leg. I also have mild cramping that is making me wanna vomit. I would be 3 + 6 today if I am. But has anybody had this accompanied with nausea right before their period was supposed to start? It's my first time dealing with this so I'm not sure...
