Call ABA, babe. If the counsellor who picks up can't answer you right away she'll know a counsellor who is more experienced with supply issues. Stress can and does affect your supply, and this has been an ongoing situation, so it doesn't surprise me that there are issues.
Hopefully, though, it's something far more simple than that and it's her demanding more before the supply can kick in. Usually, it's the simplest explanation that holds. Also, remember that she's getting out more than you can get out with a pump.
