Basically I am about 8 weeks pregnant and am bleeding. The blood is a brown colour and it isn't heavy like a period but I have got a dull ache (like very mild period pains in one side)in the lower left side of my abdomen, it is around this time I would usually be starting my period. I experienced spotting last month around the time my period was due but it stopped and after taking a pregnancy test it confirmed i was still pregnant. This bleeding today is slightly heavier but still not very heavy. Could I be at the start of a miscarriage? Any help would be much appreciated because as i am sure you understand i am extremely worried about this.
