Input please about the clearblue advanced digital opk

Jordan

Hi, I've been doing the clearblue advanced digital opk and I got two days of empty non fertile days then it jumped right into two peak solid smiley faces. I was expecting to ovulate on day 14 with my 28 day cycle but it turns out I ovulated day 10. My question is do you ovulate on the first solid smiley or the second? We had sex on Thursday and I got the first peak solid smiley sat morning. Is there a chance?
