Bloating, bowel movements. Of covid.

I have ulcerative colitis. I have been under treatment since Feb 18th 2021. At present I take Mesacol 800 mg 1-1-1 after food & Azoran 25 mg 1-o-o after food. I took covid shield 1st dose on 21st may 2021. I am taking all the dietary precautions except for an apple a day. For the last 4-5 days I have been experiencing bloating in my stomach. I am forced to pass gas multiple times. And yesterday I saw blood in my stool again after a long time. Yesterday I had more than usual bowel movement also. This was just the 2nd or 3rd time I saw/experienced it since the day I am under medical care. I am very scared. I am worried and I have suspicions that my situation has become as bad as it was before I was taking any medical care suggested by any doctor. Is it normal to see blood in faece once in a while even after someone is taking medicines for more than 3 months. I cannot contact my doctor in Bangalore because I am stuck in Chhattisgarh because of Covid.
