milk production dropped...

Have any of you mommas had your milk supply drop really bad but have been able to successfully get it back up?? If so how long did it take and what did you do to help? Bc it's been about a week and a half since it's really dropped and I'm doing everything I know to do. Drink water like a fish and I've been taking fenugreek supplements but I haven't really noticed it increasing. Maybe a tiny little bit. Oh and nurse nurse nurse around the clock if I need to I just go back and forth on boobs and I know she's not getting a whole bunch out but I do it anyways until she seems satisfied! BC I AM NOT GIVING UP! I am absolutely hell bent on not going to formula! And I pump pump pump every chance I get!
