OPK Lines

Alice

Ok so yesterday and the day before I took a OPK both days. Both days they were negative with light lines that didnt match or exceed the control line. I tested today and my test line is so light its almost non exsistent almost cant see it unless i turn the test a certain way. my question is does the lh bottom out right before O and that be why its non exsistant? Has anyone else had this happen?
