Struggling to get pregnant

I’am struggling to get pregnant again sins my first child who born is 2018

Been trying for almost 2 year I’am still breastfeeding only when he goes to sleep

I have Graves’ disease as well which is under control

I wonder if anyone else has been in the same situation as me how long did it take for anyone else to get pregnant again

I feel hopeless

I’am trying to stop breastfeeding now in hope it will work to get pregnant
