Based on your history, pregnancy is extremely unlikely. You had protected intercourse in mid-March 2026, and you performed multiple urine pregnancy tests (two tests each in April and May) using early morning urine, which is the most concentrated sample. Since these tests were taken several weeks after intercourse, a pregnancy would usually be detected by this time if it had occurred. Your missed periods are more likely related to your long-standing history of irregular menstrual cycles. The occasional one-day streaks or small blood clots you notice each month may represent breakthrough bleeding or irregular shedding of the uterine lining rather than a normal menstrual period. Since you have had irregular periods from the beginning and previously experienced an 8-month gap without periods, it is recommended to consult a gynaecologist for a detailed evaluation. Long gaps between periods can occur due to hormonal changes or conditions such as PCOS, thyroid problems, elevated prolactin levels, stress, weight changes, or other factors. A gynaecologist may suggest hormone tests and a pelvic ultrasound to identify the cause, help regulate your cycles, and ensure your uterine lining remains healthy.

Pregnancy is most likely to happen during the fertile window, which is the few days before ovulation and the day ovulation occurs. In many women with a regular 28-day menstrual cycle, ovulation usually happens around the 14th day from the start of the period. The highest chance of pregnancy is generally from about day 10 to day 16 of the cycle. Sperm can survive inside the body for a few days, so intercourse during this time increases the possibility of conception. A simple way to track fertile days is by counting the cycle dates, noticing clear stretchy vaginal discharge similar to egg white, or using ovulation prediction kits if needed. If periods are irregular, fertile days can be harder to predict. Maintaining a healthy weight, reducing stress, sleeping well, avoiding smoking and excess alcohol, and having regular intercourse during the fertile period may improve chances naturally. If pregnancy is not happening even after trying regularly for several months, it is better for both partners to consult a doctor for proper guidance and evaluation.

There is a possibility of pregnancy after unprotected sexual intercourse, even if you are not sure whether semen entered the vagina. Pregnancy may still occur if sperm reaches the vagina, and irregular periods can make it harder to predict fertile days or the expected date of your period. The most important step now is to take a home pregnancy test. These tests are most reliable from the first day of a missed period, or about 14 days after unprotected sex. If the test is taken too early, it may not be accurate, so repeating it after a few days can help if the first result is negative and your period has not started yet. If the intercourse happened within the last 3 to 5 days, emergency contraception may still be an option, so it is important to speak to a doctor or pharmacist as soon as possible. They can guide you on what is appropriate for you. If you remain worried or your periods continue to be irregular, it is best to consult a doctor for proper advice and future contraception planning.
