lower back pain after riding bicycle. should i stop or is it normal?

my cousin fixed my bike 2 weeks ago and i started riding it a few hours every 2 days or so... i rode it for like 5-6 hours today and my lower back hurts not much but feels pretty intense. should i stop and take it easier? i have not ridden a bike since 3 years ago (which was for about two weeks, and before that there were some 3 years before of pause(ridden for a few times during one month back then) and before that some couple of years to when i was a kid). so i don't have much training on position of riding a bike.... is the pain normal or should i take it easier and go get a massage or something to not get complications?
