Should I be concerned?

Hi ladies, so I am in month 4 of TTC #1, and the last 2 months have been tracking my cycles, so in July AF came 21st and I had a 29 day cycle, Aug she came 19th and September was 22nd, this meaning one cycle was 29 days and the other 34, would this be classed as irregular periods? If so should I see the doctor?
