AF showed up!

My hubby and I been together for almost 9 years and we never protected ourselves but he was very good at doing the “ PULL OUT” lol. November this year we told eachother if it happens it happens.. so we kept bd a good amount of times from November until March, from then we just decided okay let’s do this. We want a family so I bought OPK and track it right after my period ended, sure enough couple days later I got my peak and I guess I ovulate but now April 20th I got my AF. So I ask myself where did it go wrong, do we have issues? I know it takes time so maybe it will happen soon? Has anyone else experienced this? Took them a white to get pregnant? I’ll be trying out again next month.
