Inclusion Criteria:  Cohort 1: Prucalopride-Exposed Cohort:  Pregnant women. Exposure to prucalopride for the treatment of CIC or IBS-C, for any number of days, at any dose, and at any time from the 1st day of the LMP up to and including the 12th week after the first day of the LMP. If the date of LMP is unclear, or if a first-trimester ultrasound has been done and the estimated date of conception is more than one week discrepant from the menstrual period calculation, the first-trimester ultrasound-derived date will be used to calculate a date for LMP and conception. Agree to the conditions and requirements of the study including the interview schedule, and release of medical records.  Cohort 2: Disease-Matched Comparison Cohort:  Pregnant women. Diagnosed with CIC or IBS-C; frequency matched to the exposed group by disease indication, with the indication validated by medical records when possible. No exposure to prucalopride at any time in the current pregnancy; may or may not have taken another medication for their disease in the current pregnancy. Agree to the conditions and requirements of the study including the interview schedule, and release of medical records.  Exclusion Criteria:  Cohort 1: Prucalopride-Exposed Cohort  Women who have first contact with the project after prenatal diagnosis of any major structural defect. Women who have enrolled in the prucalopride cohort study with a previous pregnancy (women may only enroll once in the Prucalopride Pregnancy Cohort Study). Women who have used prucalopride for an indication other than CIC or IBS-C. Women who do not have exposure in the first trimester of pregnancy. Retrospective enrollment after the outcome of pregnancy is known (i.e. the pregnancy has ended prior to enrollment). Results of a diagnostic test are positive for a major structural defect prior to enrollment. However, women who have had any normal or abnormal prenatal screening or diagnostic test prior to enrollment are eligible as long as the test result does not indicate a major structural defect.  Cohort 2: Disease-Matched Comparison Cohort:  Women who have first contact with the project after prenatal diagnosis of any major structural defect. Exposure to prucalopride anytime during the current pregnancy. Women who have enrolled in the prucalopride cohort study with a previous pregnancy (women may only enroll once in the Prucalopride Pregnancy Cohort Study). Retrospective enrollment after the outcome of pregnancy is known (i.e. the pregnancy has ended prior to enrollment). Results of a diagnostic test are positive for a major structural defect prior to enrollment. However, women who have had any normal or abnormal prenatal screening or diagnostic test prior to enrollment are eligible as long as the test result does not indicate a major structural defect.
