I am a 23 year old female. I took the Depo shot on December 10 2009. I was having normal periods about every 28 days although around the first week of febuary i have been having it every 2 weeks on the dot. My husband and I want to try to start a family and I am VERY worried that this is a sign that I am not ovulating and will not be able to have children. Please if there is something that I can do please tell me. Thankyou.
