Can I get pregnant?


If a condom was used during the first sexual encounter and the male ejaculated inside the condom, the risk of pregnancy is low.
After removing the condom, if oral sex was performed and then the second encounter occurred without a condom but without ejaculation, the likelihood of pregnancy is also low.
However, pre-ejaculate fluid can contain sperm, so there is still a small risk of pregnancy.
It is advisable to consult a healthcare professional for personalized advice and consider using reliable contraception methods for future encounters.

Hello, the chances of pregnancy should be low, but there is always a possibility of an oversight.
It's best to use preventive measures at all times and not rely on the safe period.
If your period is late for more than a week, it is advisable to see a gynecologist.
Wishing you good health.

When it comes to the question of whether you can get pregnant from unprotected sex after using a condom, it's essential to understand the mechanics of how pregnancy occurs and the effectiveness of condoms as a contraceptive method.

First, let's clarify the situation you described. In your first sexual encounter, you used a condom, and your partner ejaculated inside it. If the condom was used correctly and did not break, the risk of pregnancy from that encounter is significantly reduced. Condoms are designed to prevent sperm from entering the vagina, and when used properly, they are about 98% effective in preventing pregnancy.

However, you mentioned that after this encounter, you engaged in oral sex and then had a second encounter where you did not use a condom. Although your partner did not ejaculate during this second encounter, there are still some factors to consider. Pre-ejaculate fluid, or pre-cum, can contain sperm. While the concentration of sperm in pre-ejaculate is generally lower than in ejaculate, it is still possible for pregnancy to occur if sperm is present and enters the vagina.

In your case, since you had unprotected vaginal intercourse after the condom use, there is a potential risk of pregnancy, albeit it may be lower if your partner did not ejaculate. The timing of your menstrual cycle also plays a crucial role in determining the likelihood of pregnancy. If you were in your fertile window (typically around ovulation, which occurs about 14 days before your next expected period), the chances of becoming pregnant would be higher.

If you are concerned about the possibility of pregnancy, the best course of action is to take a home pregnancy test if your period is late or if you experience any early signs of pregnancy, such as nausea or breast tenderness. Home pregnancy tests are generally reliable and can provide results as early as a few days after a missed period.

In addition, if you find yourself in a situation where you are worried about unintended pregnancy, consider consulting with a healthcare provider. They can offer guidance on emergency contraception options, such as Plan B, which can be taken within 72 hours after unprotected intercourse to reduce the risk of pregnancy.

It's also important to discuss contraceptive options with your partner to prevent future instances of unintended pregnancy. There are various methods available, including hormonal birth control, intrauterine devices (IUDs), and barrier methods like condoms, each with its own effectiveness and suitability based on individual health needs and lifestyle.

In summary, while using a condom significantly reduces the risk of pregnancy, engaging in unprotected sex afterward does carry some risk. If you are concerned about the possibility of pregnancy, taking a pregnancy test and consulting with a healthcare provider are advisable steps to take.
