Milk supply decreased

Samantha

I’m 14 days PP tomorrow (first time mom), I’ve been exclusively pumping since I’ve gave birth to my beautiful baby girl. My milk supply was great from the very beginning. Each pump session I was able to feed baby girl and have some leftover to store for later. However ever since yesterday (was a very stressful day, had multiple breakdowns) my milk supply has decreased greatly. My one boob that would produce three oz in one session is now barely producing one oz! I’m just wondering what the heck happened!? I’ve been pumping every 2-3 hours, except for the nights. My sister helps me out and watches my baby for 4 hours while I sleep. Is it because of the stress from yesterday? Or is that 4 hour sleep session throwing off my supply? Any other momma’s experience this and was able to get their supply back up? 😭😭
