zoloft and breastmilk supply.

I have a zoloft prescription sitting in my cabinet and I've been afraid to take it because I don't want it to affect my supply, which is already pretty low due to my son's tongue and lip ties. Long story made short, he just had his 2nd tongue tie revision and I've been pumping after every feed and just keeping up with demand. The lactation consultant said it was researched and it is unclear whether it would lower my supply. My son's pediatrician said it could possibly lower it. The pharmacist didn't know. My ob gyn that prescribed zoloft said it wouldn't. There are mixed messages when Googling. I'm thinking it isn't researched. Anybody have opinions or personal experience?
