Hi there: I have just given birth to my first...

Hi there: I have just given birth to my first baby on the 17th November (1 and 1/2 weeks old) and i have been feeling bad that i didn't try breastfeeding more + i feel the nurse was pushing me to bottlefeed, as she was hungry and i was told i couldnt express colustrum til my milk came in.... (been told that what she said was not true!?) Anyways one week and a half later i have noticed that i still have colustrum freely coming out of both breasts after taking the medication on day 3 to stop my milk from coming in. Does this mean the medication didn't work at all or just not completely? If i was to express my colustrum for the next few days will my milk come in?? Can i start expressing colustrum whilst bottlefeeding the little one then if the milk can come in start breastfeeding exclusively?? I would appreciate anything anyone can say on my situation. Thanx heaps
