Irregular

At 13 I had my first period, it was consistant for 1 year then just didn't come back. There was no possibility of pregnancy what so ever. Anyways after 5 years my period came back but only for a month and then 5 months after that. It'll be on and off for a couple months. Does this mean when I am ready to conceive a child I'll have difficulties? Will I even be able to have a baby?
