Breastfeeding cues

My daughter is 12 weeks old. She dint breast feed till 8 weeks. I pumped and fed her most of the time. After that she started with few breastfeeding attempts here and there. She would latch for few mins and rejects and asks for bottle.

Now she is trying breastfeeding. But i dont know when to stop. She feeda for about 5 to 10 mins and then fuzzes and leaves breast. If i switch side, refuses to latch. Does this mean she is full? She gets drowsy by end of feed when she drinks from bottle, but with breastfeeding wide awake and fuzzy. Not sure if she is full or wants more or had excess and struggling. Also, when i pumped after feeds, i barely get 2oz.

Any experienced mommies suggest.
