Miscarriage??

I had really bad bloating that started Friday night.So bad that even if I moved or coughed it hurt in my lower abdominal. It slowly went away till Sunday morning and through out thoes days my whole back was sore. On Monday I started to bleed very lightly then to normal flow but had no pain, I did get a thick blood clot when I had wiped myself. I just thought my period came like a week early till I stopped bleeding today. I am so confused could this be a miscarriage? I have been ttc for 5 months and I have not taken any pregnancy test
