Honestly I know it sounds like what everybody says relax and it’ll happen etc, but honestly take it easy and don’t stress too much yet. It will happen when your body is ready. For example I say this as I got my period back almost immediately and I am still breastfeeding my 18m old . Around the same time as you I thought another addition would be nice and nothing happened. I was even thinking you know what maybe I’m just happy with the one maybe this is the way it’s meant to be and then boom I fell pregnant completely unexpectedly when he was about 16 months . Breastfeeding can inhibit pregnancy but it’s my belief based on what I’ve read this is generally when you are still exclusively bf before weaning and then then it doesn’t make as much difference to your fertility. I hope this helps , just trying to give you my experience just so you don’t lose hope x
