Q:
1. After I had passed stool, there was a lot of bleeding in my back part. I wiped until I saw no blood on the tissue, then took a shower, then prayed dhuhr and asr prayers. Then at maghrib I went to the bathroom, and saw even more blood. Do I assume that the bleeding started again after I prayed asr, or do I assume that the bleeding was going on the entire time and therefore I have impurity all over me (because I showered) and my prayers are invalid?
2. Also, I often have bleeding in my back part and the toilet tissue we use is not clear white - it naturally has yellow/brown/red bits in it (I think it is because the tissue is recycled) and this makes it hard to tell if something is blood/stool or just the normal color of the toilet paper. If I wipe until the toilet paper comes back clean, then wash myself, then check again using toilet paper, however during the check I notice some spots that I'm not sure is normal color vs blood/stool, so I check again, but this time the toilet paper is clean, can I assume I am pure?
