birth control
"I started depo provera IM after the birth of my son. I never had regular monthly periods before so the injection completely stopped my period while on it. I went off it one year to attempt another pregnancy and it took almost a year for my period to return. I went back on it after deciding against a second child. The only issue I had with the IM injection was a heightened feeling of irritability/anger and soreness at the injection site for a day or two. When depo provera was switched to SQ it alleviated any irritability the day after. I've only had good experiences with depo provera."
