Constipation but confused. Or worried!

I have constipation since 15 yrs. I got sigmoidoscopy done 10yrs back and it was normal.If I walk and exercise I pass stools once in 4 days. For the past few days I have no walking or excersie at all due to office work. So I'm taking  2tsp  chia seeds water with lemon and honey twice a day. First time in so many yrs  I passed motion for two consecutive days without starin or any problem. The texture of the stools was rubbery with the shape of large intestines. It was continuous long stools but NOT THIN like ribbons. Rubbery non breaking texture.jus continuously long like the size of my palm. I also have pain on my upper right side abdomen and lot of gases. Should I be happy to pass motions without laxatives or worried
