Never get positive ovulation... anyone else?

St

Hi all,

I had extremely irregular cycles until recently, every 50-85 days! So I started a new prenatal and my last 3 cycles have been 26-28 days. However, I never get a positive ovulation test. I've tried testing at all different times of the day and still no positive, here are this month's so far just to give you an idea. Has anyone else experienced this? My OPKs look like this all cycle long! CD 16 now and my line is even more faint than CD15.
