Because miscarriage is most common during the first 12 weeks of pregnancy, it tends to be one of the biggest concerns with first trimester bleeding. However, first trimester bleeding does not necessarily mean that you've lost the baby or going to miscarry.

Can you bleed and not have a miscarriage?

Miscarriage: Bleeding can be a sign of miscarriage, but does not mean that miscarriage is imminent. Studies show that anywhere from 20-30% of women experience some degree of bleeding in early pregnancy. Approximately half of the pregnant women who bleed do not have miscarriages.

Does bleeding definitely mean miscarriage?

The most common sign of miscarriage is vaginal bleeding.

The bleeding may come and go over several days. However, light vaginal bleeding is relatively common during the first trimester (first 3 months) of pregnancy and does not necessarily mean you're having a miscarriage.
