Blood in stools. Did use it? is it safe?

Hi there, I was having constipation for about 2 days, only last night I had the urge to defecate. My stool were pretty hard. What I noticed was fresh red blood on my stools. I did not feel any pain, no trouble defecating also. I went and check with my GP and he gave me suppositories ( Ultraproct = Fluocortolone Pivalate + Lidocaine HCL ). No abdominal pain during physical examin.I did not use it because I was scared as I have never before used any medicine via anus. I only ate 1 bisacoldyl tab last night 5mg. This morning I took 2 more tabs of bisacodyl each 5mg so total 10mg and i had a pretty good bowel movement. Went to the toilet and defecate, there was no blood, no pain, just slight tingly sensation with very small to tiny burning sensation ( completely not bothering me at all ) maybe because the stools were still big and hard. So do I have to use those suppositories today or no need? Should I use it as a precautionary step ? Even if I did use it? Is it safe? Thank you very much.
