Background Abdominal pains in pregnancy are the most common during the first trimester. In most cases passes spontaneously. In this work we would like to answer the question of how may travel, physical activity, stress, smoking, and sexual contact impact on pain and miscarriage in the first trimester. Material and Methods The study material consisted of 118 patient reporting at the outpatient gynecological clinic due to disturbing pains within the lower abdomen or bleeding from the genital organ during the first trimester of pregnancy. The patients were divided into 4 groups depending on the prevailing symptoms. Results Poor correlation was demonstrated between smoking and miscarriages; Cramer’s V=0.212. Correlation was also observed between the incidence of miscarriages and the history of travel that involved road bumps; Cramer's V=0.421. On the other hand, correlation was observed between the incidence of miscarriages and physical effort; Cramer’s V=0.330. Patients with pain and bleeding due to bumpy travel or physical activity were hospitalized more often than patients with pain and bleeding after sexual contacts (p=0.0001). Conclusion The study confirmed that the risk factors of lower abdominal pains during the first trimester of pregnancy accompanied or not accompanied by genital bleeding and leading to miscarriages include patient's age, smoking, stress, travel, physical effort. Notably, bumps that occur during travel are more important in this context than the duration of travel. The bumps are often accompanied by stress; both factors trigger pain symptoms and may lead to miscarriages.
