Postpartum periods

Ch

So, baby is 7.5 months, and I stopped breastfeeding around 3 months ago. Also my last Depo shot (& only shot), was in August of 2019. I had one period about 1.5 months ago, and we are ttc. Soooo, I am waiting for my second period... still. All negative preg tests so far. Should I continue to wait? Or should I give my doctor a call? Thanks y’all. 💙💙
