ovulation test

so heres the thing i thought i grabbed a pregnancy test but i grabbed an ovulation test instead i took the test and my test line was way darker then my control line and i know im not ovulating bc i started my period yesterday and its light so im wondering is it possible that i may be pregnant and not know that i am i had a blood test dne 2 weeks ago and it showed < 3 but the range has to be <5 maybe i got the blood test early ive been so nauseous for like a week please help woulf an ovulation test read positive if your not ovulating

p.s ive read that some people took an ovulation test and found out they were pregnant that way also they test line was darker then the control line then they bought a pt a day later n found out they were pregnant
