Nutrition Science for PCOS Blog & Resources 

If you have PCOS and irregular periods, working out whether you are ovulating can feel confusing. Your tracking app may predict a different fertile window each month, ovulation tests may stay positive for several days, and having a bleed does not always confirm that an egg was released. The clearest approach is to understand what each sign can, and cannot, tell you. Changes in cervical mucus and a rise in luteinising hormone (LH) can suggest that ovulation may be approaching.
