Ttc while breastfeeding


So a little back story it took my husband and I 3 1/2 years to get pregnant with our son after failed iuis. But we finally got pregnant last year. We are ready for baby number 2. But I’m still breastfeeding our 7 month old son. I’ve been getting my period regularly every month for the past 5 months. Our sons Ebf too. Has anyone gotten pregnant while breastfeeding is it even possible lol?
