Washing one's hand after cleaning the toilet

Q: I have a western style toilet and one day after urinating and defecating in it, I flushed it. However, because there was a lot of tissue in the bowl, the toilet became blocked and the bowl filled up with water after flushing. I put my arm in this water to try and unblock it. As far as I can remember, the water looked clean. One or two tissues with feces stuck on them remained in the water, however. But as I mentioned, I don't think the toilet water had its characteristics changed. Did my arm become najis when it was immersed in this water? Because I'm unsure that the characteristics of the water were changed after flushing, do I have to assume it was najis as the water was definitely filthy prior to flushing? Please put my heart at ease as I'm worried najasah has been spread.
