Yellow Breastmilk

Hello ladies, so I just gave birth 5 days ago with my 3rd baby girl.

Usually when my breastmilk kicks in I feel it and it starts running. This time I didnt even noticed that it came. So I tried pumping to see what I can get out and also because my boobs started hurting. 

Anyhow, after about 1 hour of pumping BOTH breast I only made 1 oz and my Milk is so yellow! I know at first you have what's called "colostrum" which is yellow but I mean the actual "normal" Milk. None with my other babies did I have yellow Milk. So does anyone knows what's happening?? I'm so concered! I always had to struggle with producing and it's always been a huge challenge for me but this time it feels like there's no Milk at all...and that tiny bit is so yellow!? .. Im so confused!
