Signs and symptoms of an early miscarriage (or chemical pregnancy) would generally be spotting or vaginal bleeding similar to a menstrual period, and possibly some abdominal cramping. The bleeding might have more clots than a menstrual period; the clots would look like tiny lumps in the vaginal discharge.
It is common to feel some pelvic pressure in early pregnancy, but if you experience pelvic pressure along with bleeding or cramping this could be a miscarriage symptom. Passing clots or tissue-If you have heavy bleeding with clots or tissue there is a strong chance that you are having a miscarriage.f you experience severe pain, particularly if it is located on one side of your abdomen, you should consult your doctor right away. Pelvic Pressure-You may feel pressure in your pelvic area. This is not necessarily a symptom of miscarriage.
