In 16 months of trying to get pregnant I have never had nine days straight of showing a high ovulation test

My doctor put me on the Clearblue Advanced Digital test because the stick test were not working and they actually thought I was not ovulating so they ran tests found out I was and just had me switch Brands and then everything started working like clockwork but all of a sudden I'm getting this my last cycle was really funky anyway and now the nine days straight so I don't know if there's something wrong with me or something wrong with my test just curious if any other ladies have had something similar happen according to my 25 day cycle I should start on Monday
