What are the chances!? I'm going crazy!

3 days late! Glow said I was ovulating on the 10. My fiancé and I have sex every day so I'm not concerned about missing the day. I tested 10dao and got a negative (five days before my period) which was due Saturday the 25. So now I am 3 days late and have no test for the morning! I can get one in the afternoon and will prob take one then and the next morning! I had a miscarriage in July and I'm hoping I can concieve without a problem :/
