Pregnancy testing questions, chances of conception?


On July 7, there was sexual intercourse with condom use throughout.
Pregnancy tests were conducted on July 15, 18, 22, and 25, all showing a single line.
All tests were done using morning urine.
On July 22, there was a sore throat and a high fever lasting about three days.
On July 22, there was bleeding that was thought to be menstruation (the blood was bright red), but it stopped the same night.
The expected menstrual period is on July 29, and the menstrual cycle is very irregular.
What could be the reason for the bleeding lasting only one day? Should I continue to take pregnancy tests? What is the likelihood of pregnancy?

Hello, you should not be pregnant, and the pregnancy test is negative.
Wait another week, and if your period still does not come, it is advisable to see a gynecologist.
Wishing you good health.

Understanding pregnancy tests and bleeding can be quite complex, especially when dealing with irregular menstrual cycles and various health issues. Based on your description, let's break down the situation and address your concerns.

First, it's important to understand that pregnancy tests work by detecting the hormone human chorionic gonadotropin (hCG) in your urine. This hormone is produced shortly after a fertilized egg attaches to the uterine lining. If you have been testing with a home pregnancy test and consistently getting negative results, it is likely that you are not pregnant, especially if you are using morning urine, which is typically more concentrated and can yield more accurate results.

Regarding the bleeding you experienced on July 22, there are several possibilities. Since you mentioned that the bleeding was bright red and only lasted for one day, it could be indicative of several things:
1. Implantation Bleeding: If you had a very early pregnancy, some women experience light spotting when the fertilized egg implants itself into the uterine lining. This typically occurs around the time your period is due, which could explain the timing.

2. Hormonal Fluctuations: Given your history of irregular menstrual cycles, this bleeding could simply be a result of hormonal changes in your body. Stress, illness (like your recent tonsillitis), or changes in your routine can all affect your cycle.

3. Menstrual Cycle Variability: Since you mentioned that your menstrual cycles are very irregular, it's possible that what you experienced was an atypical menstrual period. Some women have lighter periods or spotting that can be mistaken for something else.

4. Other Medical Conditions: Conditions such as polycystic ovary syndrome (PCOS), fibroids, or other hormonal imbalances can lead to irregular bleeding. If this is a recurring issue, it may be worth discussing with a healthcare provider.

Given that you have had multiple negative pregnancy tests and considering the timing and nature of the bleeding, it seems less likely that you are pregnant. However, if your period does not arrive by the expected date (July 29), or if you experience any unusual symptoms (such as severe pain or prolonged bleeding), it would be wise to consult with a healthcare professional for further evaluation.

As for whether you should continue testing for pregnancy, if your period does not come and you still feel uncertain, you could wait a few days after your expected period date and then test again. If you continue to receive negative results and your period does not start, it may be beneficial to seek medical advice to explore any underlying issues.

In summary, the bleeding you experienced could be due to a variety of factors, including hormonal fluctuations or a very early pregnancy. Given your negative pregnancy tests and the nature of the bleeding, it seems less likely that you are pregnant, but monitoring your cycle and consulting with a healthcare provider if symptoms persist is advisable. Always prioritize your health and well-being, and don't hesitate to seek professional guidance when in doubt.

Hello, if there is bleeding in the early stages of pregnancy, a pregnancy test can be done. If the result is negative, it means you are not pregnant. If it occurs around the same time as your last menstrual period, it is likely just menstruation. Wishing you good health.
