Looking for encouragement

I’m looking for some encouragement from some of you exclusive pumpers. My daughter is 3 weeks old. I have to use formula. I’m pumping every time she eats but I am getting hardly anything. I’ve been drinking water like crazy and I’ve been eating some recipes that are supposed to increase lactation but I can’t tell a difference. With my first l, we formula fed because she would not latch and my milk dried up at 3 weeks. I’m afraid the same thing is happening because when she was 1 week old I could pump 3 ounces. Has this happened to anyone else and they were able to come back from it?

This is how much I get if I go all night without pumping.
