Randomly making milk?

So my son is almost 1.5 years old and my body stopped producing milk on its own after only 6 weeks of breast feeding. I could always still get clear stuff out, but usually only a drop. Sometimes it has a little white in it. I started my period last night but it’s still very light and I had some very weird symptoms like fainting and severe nausea. I just found out golden colored fluid is coming out, but it’s not very much at all. But it is a lot more than usual and a different color. What’s going on?
