I missed my period by 2 weeks meaning I haven't got it since my last (5/6weeks ago) I took a cheap pregnancy test which came back negative. I still had a feeling that I was pregnant. 3 days after the test I began to get brown spotting, thought nothing of it. Later that night I had a very heavy flow of blood which I never had that much before, but then I thought it was just my period been late and heavy, so I used a tampon. The next morning I went to change my tampon and I had a lot of blood cloths on it(TMI) but then after removing the tampon , a lump of blood nearly the size of the tampon, fell from my vagina(TMI) during these few weeks I've had had pains in my lower right abdomen. Could this of been a miscarriage ?
