Wic formula

So I just ran out of my second can of formula that I bought and could use some help now since I'm still out of work. Wic has pushed breast feeding but my milk supply is almost non existent since baby and I got thrush. My next wic appt isn't until June though. Does anyone know if they'd be able to get me started on formula now if I go in? They haven't provided it to us before so it'd be the first time asking for it.  Also any advice on how to up my own milk supply would be awesome ❤️
