I have been off the depo for almost a year and a half. It took me about 6 months to start my cycle. My cycle was coming regular and now I havent had one this whole month. I've had nausea and it felt like my cycle has been trying to start but no luck. My breast are sore. I havent took any pregnancy test because it doesnt feel like I'm pregnant. I've had two kids and each time I have knew that I was pregnant but this time I dont feel it. Can anyone help me out?
