Irregular periods??

Aysha
My normal cycle ranges from 31-33 days but since i have been trying to conceive and been tracking my days they have been ranging from 33,44,31 and last month 45 days is this considered as irregular cycles or is it normal to have variable days when ttc ? Has it happened to anyone else really praying and hoping this is our month currently on 5month of ttc GD LUCK all x
