Help with constipation and abdominal pain

Hello! My symptoms are really starting to scare me so I hope someone can maybe give me some insight!

I’m 25 years old. In March I started with lower abdominal pain. That was somewhat relieved when I would take a laxative. There were some days where I would take both miralax and Exlax and still just have tiny and hard bowel movements. I also felt like all the liquid in my bowels were constantly churning. I went to my OBGYN to get an exam to make sure it was nothing female related. She performed a pelvic pressed on my colon saw that gave me discomfort and told me I was constipated and told me to continue eating prunes, drink more water, and continue taking miralax. A few days later I had some regular bowel movements and my symptoms completely cleared up for about a month and a half. Then 2 weeks ago I had diarrhea and woke up the next morning feeling crampy and had constant small bowel movements throughout the day. Then seemed to become constipated, for about 2 weeks I was again having tiny bowel movements. Along with pain on my right lower side that kind of seemed to cause slight back pain as well. My mom took me to the hospital where they performed an X-ray on my colon and an ultrasound on my ovaries. My ultra sound came out normal but my X-ray showed a lot of stool especially on my right side which the dr said was more then likely causing that pain. I was prescribed stool softeners and magnesium citrate. The citrate gave me relief and I have been using the stool softeners since. But still I have not had a regular BM. Last night I again had diarrhea and woke up today crampy. I just passed a bowel movement and it was little, not very wide and flat. I just sat down and cried. Also when I wipe myself, it’s a very light almost a orangy brown and has little peppery flakes in it. I don’t know if Im still not having regular BMs because of the stool softener or what. But I’m very scared. I will admit I eat a lot of unhealthy foods and pop. Don’t drink enough water and don’t eat very many fruits or veggies so maybe that’s attributed to it. I also suffer from extreme anxiety so I don’t know if that has anything to do with it either. I’m a slight hypercondriac and always think the worst and am terrified I have colon cancer even though I know I am young and it doesn’t run in my family. Any thoughts on what it may be? I’m so scared!

I'm 71, diagnosed with mild Lupus in 1993. I thought my Lupus was in remission, but I didn't realize it just changed its route. You have worse constipation than I do, and I bet it has to do with less water and vegetables/fruit. I get those hard, what I call poopettes~~from when one of my cats was sick and dropping them all over the house~~for two to three days, then heavy diarrhea. I have hemorrhoids and they get inflamed and very painful along with cramping for hours, usually three or four. I used to have to take showers after each bout of diarrhea, but I found that a supplement from pineapple helped. What's important for me to say is that as painful as this is, it isn't fatal. If you've been screened for cancer and other dangerous ailments, this effects your quality of life, but it won't kill you. I've starting taking an Aleve type OTC as soon as the diarrhea strikes and that's helped some. I'm thinking about hitting the prednisone next time.

Thank you everyone! I haven’t drank any pop today and had multigrain pancakes and oatmeal, for snack mixed nuts. So let’s hope it helps! I am actually on both Zoloft and Wellbutrin but maybe I need to up my dosages lol
