More Info

When considering the possibility of pregnancy, it's essential to understand the various factors that can influence this outcome, especially in the context of your recent sexual activity and menstrual cycle. Based on the information you've provided, let's break down the situation.

Your last menstrual period began on June 18 and lasted for about seven days, with a typical cycle length of 35 days. This means that your next expected period would be around July 23. You mentioned having intercourse on July 8, which is approximately 10 days after the start of your last period. Given your cycle length, this date falls within your fertile window, which typically occurs around 12 to 16 days before your next expected period. However, you also indicated that you used a condom during intercourse, which significantly reduces the risk of pregnancy when used correctly.

The fact that you experienced some bleeding after the intercourse could be attributed to several factors, including potential trauma from the first-time experience or hormonal fluctuations. It's not uncommon for individuals to experience light bleeding or spotting after their first sexual encounter, especially if there was any degree of physical discomfort or if the hymen was stretched or torn.
Regarding your symptoms of dizziness and headaches, these can be caused by a variety of factors, including stress, hormonal changes, or even dehydration. They are not definitive signs of pregnancy, especially in the absence of other common symptoms such as breast tenderness or nausea.
Since your period has not yet arrived this month, it is understandable to be concerned about the possibility of pregnancy. The best course of action would be to take a home pregnancy test if your period does not start within a week or so of when you expect it. Home pregnancy tests are generally reliable and can provide you with a clear answer. If the test is positive, or if you continue to have concerns, it would be advisable to consult with a healthcare provider for further evaluation and guidance.

In summary, while the risk of pregnancy exists due to the timing of your intercourse relative to your menstrual cycle, the use of a condom significantly lowers this risk. Your current symptoms may not necessarily indicate pregnancy, but monitoring your cycle and taking a pregnancy test will provide clarity. If you have any further questions or concerns, don't hesitate to reach out to a healthcare professional for personalized advice and support.
