Trying to conceive

My husband and I have been trying to conceive for 6 months now. We have a 4 year old little boy that we were able to conceive after me being off of my birth control (the pill) for 3 months. After my son I had the implanon for 3 years and then went to the pill afterwards and was on it for almost a year. I had a chemical pregnancy back in October. What are some things or tricks that yall could suggest we could try? We want to try not have more than a 5 year gap between my son and a sibling.
