Doubting whether one had intercourse during haidh
Q: I'm really worried if I committed a sin. Yesterday when I was doing foreplay with my wife, I tried fingering and I saw a little pinkish color on my finger. My wife immediately went to the washroom and checked whether her periods started or not. She confirmed that her periods haven't started so I had sex with her the same night. But today her periods started. I'm worried whether that pinkish color was period blood. Had I committed a sin. Please tell me what I have to do.
