Baby #2?

Ok guys so my baby is giving me baby fever BAD ! my husband and I have already talked about having another baby and we wanna try soon because we want our kids close in age. we both had siblings close in age and both agree it was a blast growing up like that...anyways....so I’m exclusively breastfeeding and I still haven’t gotten my period. is there anything I can try when we do actually start to try to better our chances of getting pregnant? im discouraged it’ll only happen if I stop breastfeeding and I really don’t want to. I wanna keep going till my son is a year old.
