breastfeeding and getting pregnant

My husband and I would like to have a second baby but I'm still breastfeeding my first (10 months this month). I'm trying to track my ovulation but this app won't let me put no period or breastfeeding. Or is there a better app for this? I know it's harder getting pregnant while breastfeeding that's why I want to track it.
