Good day everyone. I had my checkup today. The doctor said that the cervix is smooth now, the uterus is in tone, and the baby's head is already at the bottom of the pelvis. I feel a slight pull in my lower abdomen and lower back. They said I can give birth tomorrow. I would like to know from someone who has been through this, how long did it take them to have their first contractions? Thank you so much for your answer. ?
