How do I determine when to start testing? For a 30 day cycle, the instruction leaflet says start testing on day 10 and the online ovulation calculator says start testing on day 13.
Hi Rachel. If you have a test that only looks for LH then start on day 13. If you have the advanced test that looks for 2 hormones then you'll need to start on day 10. Alternatively, check the instruction leaflet inside the box as the start day shown here will be correct for the product you have bought.
