You'll be OK! Call a septic company or plumber or soemthing that's sucha pain int he butt!
I used to work at a sewer and drain place (in the office lol) for a couple of months and I was always paranoid that the guys would get sick but they never did. My boiling point was when the boss brought in the tube thing w/ the camera on it to test it out IN THE OFFICE! UGH! This is gross but there was decay of soem sort on it and I freaked for a fw days that I was "exposed" to soemthing. I was fine. My point to this is you will be fine. Especially since nothing ... yucky came out.
