Ovulation Test shows low/or no LH

Last month I used my Clearblue advanced opk and it showed my low to high to peak results. We baby danced and then two weeks later a very odd period came. I took pregnancy tests and they all showed negative. This month I used the same opk and everyday it’s been saying low. Last time I took it one day was low then two days later it was peak fertility. I’m so confused as to why this month it’s been low three days in a row with no high fertility....

I have no pregnancy symptoms at all so I can’t be pregnant.

Has anyone else experienced this????
