Severe constipation

I’m drinking tons of water and eating plenty of fiber, but I’m still super constipated. Sorry for TMI but I ripped myself 2 days ago when I was constipated and again today. What can I do for the ripping and bleeding? I feel like it’s super unsanitary ripping there because feces is getting into the cut. I’m showering after, but I don’t know what else I can do. Please, kind advice only as this pregnancy has been tough on me.
