Decided to stop my birth control December 22nd, my last period on birth control was Dec 5th. I did miss a couple before I completely stopped. I would have had my period almost two weeks ago now if I was still on it. I had discharge(brownish red) on the 27th and 28th of Dec. I’ve been feeling slight pain in my legs, nauseous, increased appetite, my temp has went down below average and I’ve been extremely tired. I’ve had three negative tests. All of the symptoms are similar to when I was pregnant with my son. Does anyone have any suggestions?
