Irregular cycles


I’d love some advice ladies! My cycles vary from 30-34 days in length. A couple of months ago it was actually 28 days. Please could someone tell me if that means it is harder to conceive and if this is classed as an irregular cycle. I came off the pill in May and we have been trying properly since August.

Should I see the doctor? Ive been tracking my ovulation too and I am ovulating but around day 20 ish.
