Hi I'm 24 years old me and my husband have a beautiful 6 year old son our wish is to give him a sibling. I have been on the depo prevera for 5 years since I had my son at 18. I just got off of it in October and surprisenly started getting normal cycles every month in January. My last period was on march 12, and I began ovulation testing the 24. And all my tests were positive for ovulation. But on the 31st I started spotting off and on and still am my period isn't due till the 12. So I have no idea what's going on?
