Pregnant right after having a baby?

Madison • Wife.❤ Mommy to our 🌈 baby 10~24~18💙 &🌈 baby #2- 11~21~20💙 newly pregnant with baby #3, due 6/21/22 🥰

Has anyone gotten pregnant right after having a baby? Specifically if you were breastfeeding? My son is 3 months old and I know it's normal not to get a period yet, but I've been having light cramps for a couple weeks now and I stopped bleeding and cramping at 6 weeks PP and just started up a couple weeks ago. Also I've been having headaches every day, which I has with my son, and I feel like I can smell everything... I know it's very unlikely and maybe I'm being crazy but something feels off
