Would you say this is normal...

I think I have very irregular periods, me and my partner wasn't TTC Last year but used no forms of contreception only " pull out method" which alarmingly seemed to work, now we are TTC and Were in the 3rd month of trying, my periods on the other hand are crazy, I'll go from October 
Oct 17th - cycle day 31 
Nov 18th  - cycle day 32
Dec 26th - cycle day 36
Feb 4th - cycle day 41
Plus I would only bleed for 1-3 days... Any advice? Is it normal should I not worry? 
Thankssss 😊🙃🙂🙃😊
