I am still breastfeeding and my period has not yet returned. However, my baby is 9 1⁄2 months and we would like to start trying for our second. Typically, I do not get my period every month and likely do not ovulate regularly. Also, my cycle length varies. I would like to start using an ovulation predictor test to increase our chances of becoming pregnant quickly. I'm in my mid-30s and don't want to wait too long. Is it possible to use an ovulation test? Which do you recommend?
