The short explanation
Yes, there is a chance of pregnancy. Around twelve days after the start of your last period may be close to the time you ovulate, especially if your cycles are about 26 to 30 days long. This is often the most fertile part of the cycle. So it is worth using emergency contraception as soon as possible. Emergency contraceptive pills are available from pharmacists and doctors and work best when used as early as possible after sex. A copper IUD placed by a doctor within about five days is the most effective option and can then be kept as ongoing contraception. If there is any risk of HIV, ask a doctor urgently about PEP within 72 hours.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Do a pregnancy test about three weeks after the sex if your period has not come.
- STI testing about two weeks later is a good idea if your partner's status is unknown.
- Government hospitals and family planning clinics provide emergency contraception confidentially.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell whether you are pregnant. Emergency contraception and a later pregnancy test can help.
