Can I Get Pregnant After IUD Insertion During Ovulation?

Using an intrauterine device (IUD) during ovulation and having intercourse?

I had an intrauterine device (IUD) inserted on March 7, which was the fourth day of my menstrual period.
The doctor mentioned that it would take about a week to achieve effective contraception.
On March 20, which was the second day approaching my ovulation period, I had unprotected intercourse with ejaculation inside but rinsed immediately afterward.
On March 21, I also had unprotected intercourse but without ejaculation.
I would like to know the chances of pregnancy in this situation, especially since March 22 is my ovulation day.
Additionally, I have been experiencing some bloating in my uterus over the past two days, and I am concerned whether this could indicate pregnancy or if it might be a side effect of the IUD causing discomfort in my uterus.
Thank you.

The effectiveness of birth control pills is 99%, meaning they are highly effective in preventing pregnancy.
However, if your period is overdue, you should still visit a gynecologist.

When considering the possibility of pregnancy after the insertion of an intrauterine device (IUD), it is essential to understand how IUDs work and the timing of ovulation in relation to the insertion. IUDs are highly effective forms of contraception that can prevent pregnancy by creating an environment in the uterus that is inhospitable to sperm and eggs. They can be hormonal or non-hormonal (copper), and both types work primarily by preventing fertilization.

In your case, you had the IUD inserted on March 7, which was the fourth day of your menstrual cycle. Your doctor advised that it would take about a week for the IUD to become fully effective. This means that during the first week after insertion, there is still a risk of pregnancy if you engage in unprotected intercourse. You mentioned that you had unprotected intercourse on March 20 and 21, which were close to your ovulation period on March 22.
Given that sperm can live inside the female reproductive tract for up to five days, the timing of your intercourse relative to ovulation is crucial. If you had unprotected intercourse on March 20 and 21, there is a possibility that sperm could still be present in your reproductive tract when you ovulated on March 22. Therefore, while the IUD is designed to prevent pregnancy, the risk of becoming pregnant during this time frame cannot be entirely ruled out.

Regarding the symptoms you are experiencing, such as bloating in the uterus, it is important to note that both the hormonal changes associated with ovulation and the presence of the IUD can cause discomfort or changes in your body. Some women report cramping or bloating after IUD insertion, which can be a normal side effect as your body adjusts to the device. However, if you are concerned about the possibility of pregnancy or if the discomfort persists, it is advisable to take a pregnancy test or consult your healthcare provider for further evaluation.

In summary, while the IUD is a highly effective contraceptive method, there is still a risk of pregnancy if unprotected intercourse occurs shortly after insertion, especially around the time of ovulation. If you have any concerns about potential pregnancy or the side effects of the IUD, please reach out to your healthcare provider for personalized advice and support. They can provide you with the most accurate information based on your specific situation and help you address any discomfort you may be experiencing.
