When the baby's head engages in the pelvis, it typically causes a sensation of pressure in the pelvic area. Sometimes, the baby's head pressing on the bladder can lead to frequent urination, while pressure on the rectum may cause constipation. After engagement, there's often a feeling of relief in the abdomen. At 35 weeks of pregnancy, engagement is slightly early. Generally, first-time mothers experience engagement around 37 weeks, while those who have given birth before may engage later, sometimes only during labor. At 35 weeks, the pregnancy is not yet full-term, and early engagement increases the risk of preterm labor. If engagement is accompanied by noticeable contractions, it often requires the use of tocolytic medications to suppress contractions and maintain the pregnancy.
