Can I get pregnant? Contraception?


Having unprotected sexual intercourse on the first day after your menstrual period ended, without ejaculation inside, and only a small amount of semen being released after withdrawal, followed by cleaning with tissue and washing your hands, does raise some concerns about the possibility of pregnancy.
However, the risk is relatively low, especially since there was no internal ejaculation.
If you are concerned about the possibility of pregnancy, taking emergency contraception (Plan B) is an option, and it is most effective when taken as soon as possible after unprotected intercourse.

Regarding your menstrual cycle, stress can indeed cause delays in menstruation, and it seems that your period was late in January.
If your cycle is irregular or if you have further concerns about your menstrual health or potential pregnancy, it would be advisable to consult with a healthcare professional for personalized advice and guidance.

When it comes to the question of whether you can get pregnant after unprotected sex, especially during the time right after your menstrual period, there are several factors to consider. First, let's clarify the mechanics of conception. Pregnancy occurs when a sperm fertilizes an egg, which typically happens during ovulation. Ovulation usually occurs about 12 to 16 days before the start of your next period, but this can vary significantly from person to person and cycle to cycle.

In your case, you mentioned having unprotected sex on the first day after your period ended. If your menstrual cycle is regular, this timing is generally considered to be on the safer side for avoiding pregnancy, as ovulation is unlikely to occur immediately after menstruation. However, sperm can live inside the female reproductive tract for up to five days, so if you were to ovulate shortly after this encounter, there is still a possibility of pregnancy.

You also noted that there was no ejaculation inside the vagina, which reduces the risk of pregnancy. However, pre-ejaculate fluid (pre-cum) can contain sperm, and if any of this fluid came into contact with the vaginal area, there is a small chance of pregnancy.
Regarding your question about whether you need to take emergency contraception (like the morning-after pill), it is generally recommended if you have had unprotected sex and are concerned about the possibility of pregnancy. Emergency contraception is most effective when taken as soon as possible after unprotected intercourse, ideally within 72 hours, but some forms can be effective up to five days later. Given that you are already experiencing a delay in your menstrual cycle due to stress, it may be wise to consult with a healthcare provider about your options.

In addition to the risk of pregnancy, it's also important to consider sexually transmitted infections (STIs). Engaging in unprotected sex increases the risk of STIs, which can have implications for both your health and any future pregnancies. If you have concerns about STIs, it would be prudent to get tested, especially if you have had multiple partners or if your partner has other sexual partners.

In summary, while the risk of pregnancy after unprotected sex immediately following your period is relatively low, it is not zero. If you are concerned about the possibility of pregnancy or STIs, it is advisable to consult with a healthcare professional. They can provide personalized advice based on your specific circumstances and help you understand your options for contraception and testing. Remember, maintaining open communication with your partner about sexual health and contraception is crucial for both of your well-being.
