Prenatal Depression

Has anyone dealt with prenatal depression? I’m almost sure I had postpartum with my son that never got diagnosed. 2 years after having him I finally sought out treatment and was put on meds. Fast forward to me getting pregnant again in March, I weened myself off the meds bc I am skeptical of taking anything while pregnant. Lately, I’ve been feeling so down. I cry multiple times a week, I have trouble sleeping through the night, I am constantly tired, I don’t feel happy for days at a time. I see my doctor next week but I just don’t know if this will effect my baby
