Stopping depo to TTC

Abigail

My last depo shot was June 10, 2022 and my fiancé and I have decided we want to try for our second baby. I feel like I wasn’t warned about all of the negative side effects about the depo shot. I have always had irregular cycles but this feels crazy to me. This may be TMI but I’ve been “bleeding” for two weeks now and it’s all been dark old blood. Is this normal? My OBGYN just left my clinic and I’m not comfortable asking a doctor I don’t know. What is y’all’s experience coming off of the depo?
