When it comes to understanding pregnancy risks and emergency contraception options, it's essential to consider several factors, including the timing of intercourse in relation to your menstrual cycle, the method of contraception used, and the effectiveness of emergency contraceptive pills (ECPs).

Firstly, if your boyfriend ejaculated on you and then wiped away the semen with a tissue before touching your vagina, the risk of pregnancy is still present. Sperm can survive outside the body for a short period, and if any sperm were to remain on his fingers or the tissue and then come into contact with your vaginal area, there is a possibility of pregnancy. The likelihood of conception depends on various factors, including the timing of your menstrual cycle. If you were in your fertile window (which typically occurs around ovulation, about 14 days before your next period), the chances of becoming pregnant are higher.

Regarding emergency contraception, it is indeed effective if taken within a specific timeframe after unprotected intercourse. There are two main types of emergency contraceptive pills:
1. Levonorgestrel (Plan B One-Step and generics): This is most effective when taken within 72 hours (3 days) after unprotected sex, but it can work up to 5 days after. The sooner you take it, the more effective it is.

2. Ulipristal Acetate (Ella): This pill can be taken up to 120 hours (5 days) after unprotected intercourse and is considered more effective than Levonorgestrel, especially when taken later in the 5-day window.

Both types of emergency contraception work primarily by delaying ovulation. If ovulation has already occurred, these pills may not be effective. Therefore, if you suspect you are in your fertile window, taking emergency contraception as soon as possible is crucial.

In terms of effectiveness, Levonorgestrel is about 89% effective when taken within 72 hours, while Ulipristal Acetate maintains its effectiveness throughout the 5-day window. It's important to note that these pills do not terminate an existing pregnancy; they prevent pregnancy from occurring.

In addition to taking emergency contraception, consider consulting with a healthcare provider for further guidance. They can provide personalized advice based on your health history and specific circumstances. If you experience any unusual symptoms or have concerns about potential pregnancy, a pregnancy test can help clarify your situation.

Lastly, if you find yourself frequently in situations where emergency contraception might be necessary, it may be worth discussing long-term contraceptive options with your healthcare provider. There are various methods available, including hormonal birth control pills, intrauterine devices (IUDs), and implants, which can provide more reliable protection against unintended pregnancy.

In summary, while the risk of pregnancy exists in the scenario you described, emergency contraception can be an effective option if taken promptly. Understanding your menstrual cycle and the timing of intercourse can help you assess your risk and make informed decisions about contraception.
