How do you know if the shot is working?

Answer 1

The birth conrtol pill stops you from ovulating. Most women have much lighter periods while on the pill. You should have at least 1-3 days of spotting each month to reassure you that you are not pregnant, if you don't miss any pills. A blood test would indicate if there is enough hormone retained from the pills to have the desired result. If you keep careful track of body temperature and notice a slight drop around the time that you would expect to be ovulating, you might be ovulating. Dwight
