Is it likely you had a miscarriage if after sex something fleshy came out and you then started a very heavy period?

It could be if you are sure you were pregnant. I had a miscarriage when I was 2 months along. One night I had sex and bleed a little afterwards. The next day I started bleeding bad and passed large clumps for hours. I went to the doctor and it was confirmed that I had been pregnant and had a miscarriage.

I had sex with my fiance and he hit me on the outside of my body by accident instead of going inside of me. I bleed really bad right after that. A few days later I passed a large "sac-like" tissue. Later on the doctor told me I had had a miscarriage.
