help..

I'm really upset and frustrated. My daughter is 6 days old now and has been using the bottle. When I had her I tried BFing, she latched but then unlatched and wouldn't latch again so I decided to just bottle feed. For the last 3 days I've been trying to BF (milk hasn't came in, just a little bit of colostrum) but she will latch on (I'm not even sure if it's the right way) get REAL fussy, whip her head and start crying. I don't know what to do I'm at a loss. I really want this bond but it's so hard.
I bought a pump but nothing comes out expect some drops of colostrum. I don't have the money for a breast shield though I want one. Please help. TIA.
