term life insurance no medical

I have been diagnosed with rheumatoid arthritis for six years now. It’s an autoimmune disease where the immune system mistakenly attacks the good cells particularly the linings of the joints. After a year from being diagnosed I have a acquired term life insurance no medical. I am so lucky that I was able to get the life insurance with no medical exam and at a best life insurance quote. At first I thought it’s not possible because my sister told me that when she bought her insurance she has undergone a medical exam.
