Ovulation fact 5: Do ovulation prediction kits and temperature charts work?
Yes, they can be a useful guide. They can tell you when you’re ovulating, but can be inaccurate on timing. Learning to read your body and pinpointing the fertile time in your cycle is cheaper and often more affective. Ovulation kits work by testing your urine for a hormone surge which occurs just before ovulation. By the time you get the result, the window of opportunity may have passed. Something called Basal body temperature (BBT) measurements used to be used but rely on the fact that your body temperature increases a very small amount after ovulation. Again, you may have already ovulated by the time you get this information, so it’s too late to conceive. Try our ovulation date calculator tool to and see how you get on.
