Whether or not you can have a pregnancy after 20 days of IUD removal is a case by case analysis. If the implantation and the development of the gestational sac are normal, you can usually have it, but if abnormalities are found in the implantation and the development of the gestational sac, it is usually not recommended. If you are pregnant after 20 days of IUD removal, you can go to the hospital in time and have an ultrasound and routine blood test to clarify the development of the gestational sac and the location of the implantation, if the test results are normal, you can usually have it, but you should pay attention to regular maternity checkups. If the result of the examination shows that the implantation is not very good, or the development of the gestational sac is slow, fetal abortion may occur at a later stage, so it is not recommended to have it, and it is usually necessary to follow the medical advice to terminate the pregnancy. After the removal of the ring, there is usually a small amount of vaginal bleeding, so avoid intercourse and do not take a bath to avoid infection. The IUD is usually a good contraceptive measure, but it usually affects the uterus and may cause damage to the endometrium. After the IUD is removed, it needs to be adjusted for a period of time to allow the endometrium to recover slowly. It is recommended to get pregnant 1 month after the IUD is removed and after 1 menstrual period.
