is this possible??

Is this correct?? last cycle i started testing on day 15 because i normally have a long cycle and i didn’t have any test strips until then. i never got a positive ovulation test and then my period came. So move on to this cycle i just got off my period on cycle day 5 and now it’s cycle day 7 and i got a positive ovulation test. is it possible that my cycles are short now and i just ovulate super early??
