I got my tubes tied three years ago. I was supposed to start my period two weeks ago. Instead I started getting headaches and feeling very nauseous and tired. I also started to get a string aversion to most smells. Yesterday, my stomach started cramping and last night I started lightly bleeding. This morning I woke up and had big blood clots. I am bleeding super heavily and have to change my tampon every 30 minutes to an hour. I ve been getting dizzy and nauseous today as well. I called my OBGYN to talk to him, but his office is apparently to busy to answer my questions.
