Advice - I want to get pregnant

I had my implant out in July 2023. I’ve been trying to get pregnant since September 2023. I was actively having sex, tracking periods, doing temperature and ovulation sticks between September and December. My husband and I don’t want this to be a chore. We stopped ‘trying’ until June this year but then began trying again. Two months of having sex and trying around ovulation and high fertility dates and no success. I have just started my period again and I am feeling gutted it has not happened yet. I have a three year old already and I am really keen to have another. Can anyone help or advise where I’m going wrong or? Thanks
