Ovulation

Hiya just wondering if someone could give me advice please my cycle is 23-24days and have a period for 5days I’m in cycle day 11 and have been doing the pink clear blue ovulation test and the strips since day 6 as it’s my first time doing the tests and all are negative I’ve been testing twice a day between 10am-8pm I’m confused as to when I’ll ovulate 🙂
