Irregular bleeding

I have been having irregular monthly cycles for the past 8 months. They are always about 2 weeks late and it is weird.

3 months ago I moved to a new country with a very very different climate and 10h time difference (don’t know if this is a factor) and my first cycle was accurate to the second. For the first time in half a year it was actually on time. But then I started spotting 1-2 weeks later and this started happening on every cycle. The pattern I noticed is 2 days spotting/bleeding before ovulation, then it stops for 2 days and again 2-3 days of bleeding. This is sometimes accompanied by cystitis, not sure if connected. And my actual period will be late for 1-2 weeks again.

Is it normal to have such intermenstrual bleeding or should I go visit a doctor?
