Based on the information you've provided, it seems you are experiencing a delay in your menstrual cycle and have conducted home pregnancy tests that have returned negative results. Let's break down your situation and address your concerns regarding the possibility of pregnancy and the accuracy of home pregnancy tests.

Firstly, it's important to understand how home pregnancy tests work. These tests detect the presence of human chorionic gonadotropin (hCG), a hormone produced shortly after a fertilized egg attaches to the uterine lining. Generally, hCG can be detected in urine about 14 days after conception, which corresponds to the time of a missed period for most women. If you tested before this time, it could result in a false negative.

In your case, since your menstrual cycle is approximately 32 days and your last period started on October 8, you would expect your next period around October 20. Given that you have not yet had your period and have tested negative on October 22 and 25, there are a few possibilities to consider:
1. Timing of the Test: If you tested too early, it might not have been enough time for hCG levels to rise to a detectable level. If you suspect you might be pregnant, it may be worth waiting a few days and testing again, ideally with the first morning urine, which is more concentrated.

2. Menstrual Irregularities: Stress, changes in weight, illness, or hormonal imbalances can cause menstrual delays. If your cycle is usually regular, a delay could be concerning, but it does not necessarily indicate pregnancy.

3. Symptoms: You mentioned experiencing dizziness, which can be a symptom of pregnancy, but it can also be attributed to other factors such as dehydration, low blood sugar, or anxiety. It's important to consider the full context of your health and any other symptoms you may be experiencing.

4. Negative Test Results: If you have received two negative results, it is less likely that you are pregnant, especially if you are testing after the expected date of your period. However, if your period does not arrive within a week of your expected date, it would be advisable to consult a healthcare provider for further evaluation.

5. Consulting a Healthcare Provider: If your period remains absent and you continue to have symptoms that concern you, it would be wise to see a healthcare provider. They can perform a blood test for hCG, which is more sensitive than urine tests, and can also evaluate other potential causes for your symptoms and menstrual irregularity.

In summary, while there is a possibility of pregnancy given the circumstances, the negative results from your home pregnancy tests suggest that it is less likely. However, if your period does not arrive soon or if you have any other concerning symptoms, seeking medical advice is the best course of action. A healthcare provider can provide a more definitive answer and help you understand your reproductive health better.
