FTM Exclusively pumping milk supply help!

N
So I breast fed my baby for about two weeks and then my milk supply completely dropped off I had to get formula to feed my baby.... I'm not going to let him starve because I can't supply. So he was introduced to the bottle way earlier then I wanted to. After introducing the bottle my LO began to have a short latch so I decided to exclusively pump and I get 3 to 4 oz every time I pump every two hours. On Friday I had a breast infection and I got it cleared up but I'm afraid my ducts are clogged...I can't tell. I called my hospitals LC on Thursday and she has yet to call me back, so I'm in search of some help. Any suggestions on increasing my supply? I'm already taking fenugreek.
