Leaking on driver side floor mat...

I have some fluid that seems to be dripping from somewhere and coming down my clutch pedal and onto the floor mat. It is a slow leak but still not great. Its a yellowish fluid. I drive a 2005 325i just looking for some input on what it could be.

I`m thinking maybe clutch master or slave cylinder.... whichever would be close to the pedal (slave I think). I think I ruled out anti-freeze just because heater core is normally on the passenger side and I turned all heat and AC off and it still seemed to leak.

Master cylinder for sure. Many years ago I had an MGB that had the same leak. Feel the fluid between your fingers - slippery and thin? It's your master cylinder. Be careful. You will gradually lose braking pressure and eventually will need to "pump up" the brake pedal to get the brakes to bite - not a good situation to say the least. On top of this, the fluid can drip onto your pedal and your foot will slip off when trying to stop. This could be catastrophic. Replace the unit ASAP.
