I think I have endometriosis, we want kids in a yearish should I be concerned and take action now or just wait to see if it effects fertility?

No clear answer. Endometriosis can affect fertility and treatment can take a while with tests and interventions. It seems you are 23 so a year may not matter. However, if you are impatient you may want to get a consultation to understand what is necessary to succeed now so you can decide whether to wait or start. Best wishes.
