What to believe?!

This morning I used my morning urine ( seems to work best for me) and took an OPK... Well two ? a clear blue digital and a cheap stick I ordered a pack of from Amazon. The cheap Amazon one gave am a very clear positive, but clear blue didn't give me a smiley face.. So which one do I believe?! Does anyone have any input? Please?!  Either way I'm planning to BD tonight but one gives me a little bigger time frame than the other! Help!!
