i'm currently 34 weeks pregnant and I bleed off and on in my first trimester... I even had multiple doctors tell me I was M/c but everytime they would to the u,s my L/O was still there so yes it can happen
I had a lot of bleeding with my twins but I was pregnant for about a week before it started. It was never real heavy but enough to where I thought I was getting my period. I went to the DR. and my blood work came back showing my body was trying to miscarry. But I never did and my twins are 3. I also was pregnant and within a couple of days miscarried. It was different...much heavier bleeding followed by heavy cramping.
