Frequent contractions at 36 weeks can be physiologic, i.e., false contractions or contractions with preterm labor, etc. Frequent contractions at 36 weeks can be due to physiologic contractions, i.e., pseudocontractions, or they can be a sign of preterm labor. Pseudocontractions occur more frequently at 36 weeks of pregnancy and are irregular contractions that occur during this week of pregnancy due to the increased sensitivity of the uterine myometrium. These contractions are characterized by short duration, long and irregular intervals, strong and weak contractions, not accompanied by morphological changes of the cervix such as shortening of the cervical canal and dilatation of the uterine opening, which are physiological phenomena and do not require much concern. But when the frequent contractions are true contractions, that is to say, manifested as rhythmic contraction pain, contraction pain gradually aggravate, pain interval gradually shorten, if the frequent contractions accompanied by dilatation of the uterine orifice, fetal prenatal descent, vaginal bleeding, you should seek medical attention as soon as possible.
