I'm having pregnancy symptoms again. My boyfriend doesn't want to go through another miscarriage again. I told him and he says I'm not pregnant again. I'm having all the symptoms I had when I was pregnant and a little more. Fevers, headaches, sore boob, eating more, urinating more, drinking more, more tired and back pain (sometimes) What do I do?
