Zoloft for Post partum depression

My Doctor is starting me on Zoloft to help with post partum depression. Has anyone else’s doctors talked with them about this or have any experience with taking this? I have 6 weeks until baby is due and he stated that it takes 4-6 weeks to start working. Just wondering on thoughts and if anyone had taken it and the outcome? I’m hoping it works well as I had baby blues bad with my son but never acknowledged it and my family didn’t talk about it until a year after my son was born. Trying to help myself as much as I can.
