Can you be able to have kids with irregular periods?

Good question.

Absolutely! However, as you know, they must of course be "female kids", and you must wait until they reach the age of having a period. Then, and only then, can you determine if your "kids" are able to have "irregular periods".

Wish there were a way to determine earlier, but as now, they can't.

Hope this answers your question of "Can you be able to have kids with irregular periods?"
