Hey Louie it's not a bad idea to put out doe urine early in the pre-rut and then as time moves on switch to estrus scents to hang up. Also If your not sure if your calling is having any effect just don't do it. If you are in any kind of high pressure area your deer may not come running to a call or you could just be doing a combination they don't like. One last tip to see how often deer might be coming to the scrape is kick some leaves over it then come back the next day to see if it has been cleaned. This will help give you an idea when a buck might be coming threw the area or if they are still tending scrapes.
But as usual with hunting and we all know this, the best way to get a deer is to be out there trying! So as long as you stay with it I believe you will have some brown down here soon.
