Pregnancy Chances After Medication Abortion and Menstrual Cycle

Pregnancy Probability and Menstruation

Hello doctor, I took the first dose of medication for abortion on January 8, the second dose on January 10, and I stopped bleeding around January 21.
During this period, I had intercourse with my husband on January 15, January 21, January 26, and January 31, but he withdrew before ejaculation each time.
I would like to ask the doctor how likely it is that I could be pregnant.
If the likelihood of pregnancy is low, will my first menstrual period after the abortion likely come about a month after January 8? Thank you.

Dear Sun,
The day you start bleeding from a medical abortion should be considered the first day of your menstrual period.
Therefore, it is still possible to become pregnant from any sexual intercourse that occurs afterward.
However, your next period may not necessarily arrive exactly one month later.
If it is delayed by more than a week, it is advisable to take a pregnancy test.
If you have any other questions, please consult a gynecologist.

More Info

After a medication abortion, understanding the chances of pregnancy and the menstrual cycle can be quite complex. Based on your timeline, you underwent a medication abortion on January 8, taking the first dose, followed by the second dose on January 10. You mentioned that you stopped bleeding around January 21, which indicates that your body was likely returning to its pre-pregnancy state.

Regarding the likelihood of becoming pregnant after a medication abortion, it is important to note that fertility can return quite quickly. In fact, ovulation can occur as soon as two weeks after the abortion, which means that if you had unprotected intercourse during that time, there is a possibility of becoming pregnant. However, since you mentioned that you and your husband practiced withdrawal (pulling out) during intercourse on January 15, 21, 26, and 31, the chances of pregnancy are lower, but not zero. Withdrawal is not a reliable method of contraception, and pre-ejaculate fluid can contain sperm, which could lead to pregnancy.

As for your menstrual cycle, after a medication abortion, it is common for the first period to be delayed or irregular. Typically, you can expect your first menstrual period to return approximately four to six weeks after the abortion, but this can vary from person to person. Since you had your abortion on January 8, you could anticipate your first period around early to mid-February, but it could be earlier or later depending on how your body responds.

If you do not get your period by the end of February, it would be advisable to take a pregnancy test to rule out the possibility of pregnancy. If the test is negative and you still do not get your period, it may be worth consulting with your healthcare provider to ensure that everything is progressing normally.

In summary, while the chances of becoming pregnant after a medication abortion are present, they depend on various factors, including the timing of ovulation and the effectiveness of the withdrawal method used. Your first menstrual cycle post-abortion may not follow a strict timeline, but it is generally expected to occur within a month or so after the procedure. If you have any concerns or experience unusual symptoms, it is always best to reach out to your healthcare provider for personalized advice and support.
