CBopk :)

So I'm taking the opk test with either a plain circle if negative or a smile face if surge is detected. I had some cm so decided to test cd 7 was negative but then have been getting smile face cd8,9,10 so far lol my bbt took a tiny dip today so does this mean if it rises tmrw I ovulate today?? 
​I made my husband pee on the stick just to make sure the monitor isn't stuck smiling lol thank god he is not ovulating lol I've never had more than 2 days of a smoke face... I don't want to O too early - is it bad if I O cd10? Will the egg be mature? Uugh trying to not stress and just keep BDing lol until smile is gone lol
