15 to 19 weeks — If you are over 15 weeks 3 days, the procedure will occur over 2 days. The cervix needs to be opened by inserting laminaria (osmotic dilators) the day before the abortion. These absorb moisture and expand, gently opening the cervix. They are left in overnight. The next morning you will return to the clinic and be given Misoprostol tablets to aid in softening and dilating the cervix. These take approximately two hours to work, so you will be given a comfortable recliner to rest in. When you are ready, the physician will remove the laminaria and complete the procedure. On the second day, the procedure will take 10 to 30 minutes.
