If you get confused with True labor contraction and Braxton Hicks contraction, please refer to the text below on the screen, it will help you :) ※ Always consult your doctor to orient yourself in terms of contraction frequency and duration. This app is not a medical device and our recomendations are based on standard indicators. Your labor may occur differently. Therefore, do not rely exclusively on our app. If the duration and frequency of contractions do not yet correspond to the necessary indicators but labor pains become unbearable, or if your water breaks or significant bleeding occurs, it is better to go to the hospital as soon as possible.
