Depo-Provera Contraceptive and breast tenderness

Well I started a brown discharge Last Thursday and had called my doctor to schedule my appointment for the following day to receive my shot. The weird thing was I started on my 24th day, when I always seem to start on my 35th day. That evening my husband and I had sex, normally it helps me start the heavy flow, but this time there was nothing. I went to the doctor bright eyed and bushy-tailed that morning and explained the situation. Not even two weeks before I had come in to talk about my options I was 10lbs lighter. She found it kind of odd that I gained that much weight and she thought I might be pregnant, but the pee test came back negative. So, she decided to give me the shot anyway. Well, it has been 5 days now and no spotting and definitely no flow. Just heavy discharge which I was having before the shot and bloated too. I had breast tenderness before I received the Depo-Shot, but of course it has increased sense than. I have had more back pain after sitting for long periods. I feel nauseated, but get relief after eating a small meal. Thirsty all the time and always tired. I can't say I am depressed, because I have been on Paxil and Hydroxyz for the past three months. There is a possibility I could be pregnant, because I am married to a man who refuses to wear condoms. With any medication comes risks, and at this time in my life I believe I am truly blessed to have a beautiful healthy baby boy and don't need another. I do say if God wants me to have another one he will make it happen. Even though I am in this situation, with all these side effects, there is nothing I can do about it now. Whats done is done, there is no reversing it. With any chemical you put in your body you take the risk of some side effect good or bad. We just always hope for the good. So I guess basically I am saying that yes I have some side effects, but what drug doesn't give you some kind of side effect. It seems a lot of people are complaining about weight gain. I can tell you most of it is water weight, you can take care of it with an herbal diuretic and if you want to go on a diet where you eat every two to three hours healthy I would recommend ****** It truly works, trust me I know. Good Luck everyone and Blessings to All.
