When it comes to the question of whether you could be pregnant, especially after having unprotected intercourse, it's essential to understand the timing of your menstrual cycle, the nature of your sexual activity, and the symptoms you are experiencing. Based on your timeline, you had unprotected intercourse on April 22, and you are now at a point where your expected menstrual period has not yet arrived.
Firstly, let's discuss the likelihood of pregnancy. If your menstrual cycle is typically regular, and you have a cycle length of around 28 to 31 days, ovulation likely occurred about 14 days before your expected period. If you had unprotected intercourse during your fertile window (which is typically a few days before and after ovulation), there is a possibility of pregnancy. However, since you mentioned that you have already taken a pregnancy test on May 3 and it showed a single line (indicating a negative result), this suggests that you are not pregnant at this time.
Pregnancy tests are most accurate when taken after a missed period. Since your period is expected at the end of April, testing on May 3 may have been too early, especially if you have a longer cycle. If your period does not arrive soon, it would be advisable to take another pregnancy test a few days after your expected period date for more accurate results.

Regarding the symptoms you are experiencing, such as lower abdominal pain and increased flatulence, these can be attributed to various factors. It's not uncommon for women to experience premenstrual symptoms, which can include cramping and gastrointestinal changes. The feeling of increased gas can also be linked to hormonal fluctuations that occur in the menstrual cycle.
If you continue to experience abdominal pain or if it worsens, it may be worth consulting with a healthcare provider to rule out other potential issues, such as ovarian cysts or other gastrointestinal concerns.
In summary, while there is a possibility of pregnancy given the nature of your sexual activity, the negative pregnancy test results and the timing suggest that you are likely not pregnant. If your period does not arrive soon, consider retesting and consulting with a healthcare professional for further evaluation. It’s always best to listen to your body and seek medical advice if you have concerns about your health or symptoms that persist.
