I had unprotected pregnancy four days before medical abortion. Is there any chance of pregnancy?

Question

Hi doctor,

I was three months pregnant and recently had a medical abortion. I had unprotected intercourse four days before the abortion. I was given 200 mcg of Mifepristone and two days later Misoprostol which expelled the pregnancy. (the intercourse occurred six days before the Misoprostol).

I am worried that this may start a new pregnancy after the abortion was completed as sperm can live up to seven days and if I ovulated immediately after abortion the sperm could be alive to start a new pregnancy.

Please can you help me and give me an explanation of the following:

Can 200 mcg of Mifepristone be effective at preventing pregnancy, if taken four days (96 hours) after unprotected sex? I have found information on the internet which says in some countries that Mifepristone is used as an effective emergency contraceptive. However, they say small doses of up to 50 mcg. Please tell me whether 200 mcg would be most effective?

Hi,

Welcome to icliniq.com.

There seems to be confusion about the dose of Mifepristone which you know about. Usually, three 200 mg tablets (600 mg total) orally administered Mifepristone as a single one time dose and two days later Misoprostol is given. Your idea about 200 mcg Mifepristone is therefore incorrect.

Regarding ovulating immediately after medical abortion is not possible. This is because the hormones in your body are still abnormal and ovulation will not occur in this situation.

I guess you have been given 200 mg of Mifepristone and there is no risk of pregnancy from sexual intercourse four days after the abortion. The uterus is not ready to have another pregnancy right now so there is no risk to you.
