More Info

When it comes to understanding the chances of pregnancy and the timing for accurate pregnancy testing, several factors must be considered, including the timing of intercourse, the use of contraception, and the timing of ovulation in relation to the menstrual cycle.

Based on your description, your last menstrual period started on January 31, and you had sexual intercourse on February 8 while using a condom. If the condom did not break, the likelihood of pregnancy is significantly reduced, as condoms are an effective form of contraception when used correctly. However, if there is any uncertainty about the integrity of the condom, it is wise to consider the possibility of pregnancy.

The menstrual cycle typically lasts about 28 days, but it can vary from person to person. Ovulation usually occurs around 14 days before the start of the next period. If your cycle is regular, ovulation would likely have occurred around February 14. Since you had intercourse on February 8, this was before your ovulation window, which further decreases the chances of conception.

Regarding your pregnancy tests on February 20 and February 23, if both tests showed a single line, this indicates a negative result. Home pregnancy tests are generally reliable when taken after a missed period, but they can sometimes yield false negatives if taken too early. The hormone hCG, which is produced during pregnancy, may not be detectable until a few days after implantation, which typically occurs about 6-12 days after ovulation.

You mentioned planning to take another test on March 1. This timing is appropriate, as it would be about 14 days after your potential ovulation date. Testing at this point should provide a more accurate result, especially if your period has not arrived by then. If you still have not gotten your period and the test is negative, it may be advisable to wait a few more days and test again or consult a healthcare provider for further evaluation.

As for the symptom of frequent urination, it can indeed be caused by anxiety or stress, especially if you are feeling nervous about the possibility of pregnancy. Other factors, such as increased fluid intake or urinary tract infections, can also contribute to this symptom. If you continue to experience frequent urination along with other potential pregnancy symptoms, it is best to consult a healthcare professional for a thorough assessment.

In summary, based on the information provided, the chances of pregnancy appear low due to the timing of intercourse relative to ovulation and the use of a condom. Testing on March 1 should yield a more accurate result, especially if your period has not started by then. If you have any further concerns or symptoms, do not hesitate to reach out to a healthcare provider for personalized advice and support.
