I may have had a miscarriage but I'm not absolutely postive. My period was late but I chalked it up to stress so when I started bleeding I assumed it was my period. But then I started cramping, like lower back/abdominal cramping....sorry for TMI but there was blood and clots and mucus....If I take a pregnancy test will it even show up? Or will I have to go to a doctor? I dont have insurance so I dont really know what to do, this has never happened to me before.
