Ttc and nursing

Is so hard for us. I didn’t get my period until my son was 18 months old. He’s 24.5 months and I’ve gotten maybe 4 periods. Went 2 months with no period and now I’m 2 days late again. I don’t want to wean him but he nurses so often it’s delaying period and ovulation for me so often. I’m terrified I won’t get my period again and will go months without. We’re really praying to be pregnant by end of July, we’ve been trying since September
