Guess I’m on to month 3 TTC😣 ANYONE???

Started my period this morning so we are out again for this month. So has anyone ever had trouble conceiving their third child when your prior two children were very easily conceived? (One was a surprise and the other was planned and we got pregnant our first month of trying). I KNOW that people have such a longer wait and have had harder things happen to them so I’m not complaining. Just wondering if this has happened to anyone else and how long it took to get pregnant. I’m worried there’s something wrong?? (Our first month ttc this time we did have a chemical pregnancy).
