TMI constipation help

This is tmi but for the first time in my life I’m experiencing really bad constipation. I have been taking Metamucil and it doesn’t seem to be helping. I’m drinking a lot of water and eating fiber. The last normal bowel movement I had was about 5 days ago. When I try to poop only a few rabbit pellets come out and I have to strain. It’s extremely uncomfortable and painful. If anyone has any tips let me know
