Some women will have some of the signs of miscarriage below, while others have no problems whatsoever and find out at a later prenatal appointment that their baby has died (missed miscarriage). Here is more on the signs that may indicate a problem with your pregnancy from About.com Guide to Miscarriage and Pregnancy Loss.

If you are having blood work done, your practitioner is looking at your hCG levels. While there are ranges to look at which can give you some basic information about a pregnancy. Repeated numbers give a better look at what is going on inside. When the hCG levels begin to fall, you may be having a miscarriage or other pregnancy complication, including an ectopic pregnancy.
Vaginal Bleeding
Bleeding in pregnancy can be quite worrisome. While there are some instances when bleeding might not indicate a problem, you should always report any spotting or bleeding to your midwife or doctor. They may recommend various tests to check on the health of your pregnancy.
