HELP!! TTC

Hi all i am very new to this and this is my 1st post. I am abit uncomfortable asking family and friends so thought this would be a lot easier. Me and my partner have been TTC for a while now but i havent been able to achieve a positive ovulation test. I have regular periods and always have done. I have tried taking the test at all different times of my cycle. Im starting to worry there is something wrong. Is this normal?
