Negative ovulation test

Samantha

Hello! I took an ovulation test last night, the clearblue advanced and it showed peak ovulation along with multiple physical symptoms so me and DH had sex. Well I decided to this morning take a clearblue digital and a strip and they both said negative?? Does this mean I did not actually ovulate?? My friend gets multiple days of positive ovulation tests in a row but mines all of a sudden negative 12 hours later? This was my test last night for proof lol!
