I skipped my last depo shot(the one before was taken Sept. 2nd) and had unprotected sex up until 15weeks after my last shot. 2-3 weeks after that my symptoms began. First sore and heavy breasts, then fatigue, increased vaginal discharge bloating, headaches, nausea. For the past week I've had light cramping and yesterday I started having very light brown spotting but only when I use the bathroom and today is a very light pink. Could this be the side effects of coming off the depo shot or could I be pregnant? I'm a little scared to take a test. I already have two children...
