How do i find out when i ovulate when my periods every 21days
Typically ovulation happens at the mid-point of your cycle. But rather than guessing the mid-point you can take your temperature to find out which days it is higher(the days it's higher are ovulation days), go to a doctor to let them aid you on this journey, or take home ovulation tests which can be found at your local drugstore.
Best of Luck!
