Am I Pregnant? Menstrual Changes and Testing

Will I still be able to get pregnant?

Hello, doctor.
I'm not sure if you remember, but I've been coming here to ask questions over the past few days.
I had intimate contact on 9/1, 9/2, and 9/5.
I took a pregnancy test three times before my period, and right after the last test, my period started.
The first day was brownish-red in the evening, with pink when I wiped.
The next morning, it became heavier and turned red, and by the afternoon, it was bright red.
On the third day, I used one pad of 26 cm and one of 23 cm.
Now on the fourth day, the flow is gradually decreasing but is still red.
When I urinate, there is a small amount of blood that comes out as well.
I'm really scared, so I woke up around 4 AM to take another pregnancy test, which was negative (there was no faint second line).
However, in the morning, I felt a bit nauseous and had a headache while riding in the car (I've been feeling a bit of gastrointestinal discomfort these past few days) and had mild diarrhea.
Could this be related to my menstrual period? Can I confirm that I am not pregnant? I've taken four pregnancy tests in total, and I tested again after my period started.
The menstrual flow is normal, and the color is also normal.
Doctor, is this a normal period, and can I be sure that I am not pregnant? Is there a need to take another pregnancy test? Thank you, doctor, for your hard work.

Hello, it should be your menstrual period, and a negative pregnancy test indicates that you are not pregnant.
If you are still concerned, you can take another pregnancy test to confirm.
If it is negative, you can be completely at ease.
Wishing you good health.

More Info

It sounds like you are experiencing a lot of uncertainty and anxiety regarding your potential pregnancy, especially given the recent changes in your menstrual cycle and the various pregnancy tests you've taken. Let's break down your situation and provide some clarity.

From what you've described, it seems that you had unprotected sexual activity around your ovulation period, which is when conception is most likely to occur. You mentioned that you took multiple pregnancy tests before your period started, and all of them returned negative results. After that, your menstrual bleeding began, starting with light spotting and progressing to a heavier flow, which is typical for a menstrual period.

The fact that you experienced a normal menstrual cycle, with bleeding that increased in flow and changed in color, suggests that you are likely not pregnant. Menstrual bleeding can vary in color and consistency, and it is common for the first day or two to include lighter spotting before transitioning to a heavier flow. The presence of bright red blood is typically associated with fresh menstrual blood, while brownish or pinkish blood can indicate older blood or spotting.

Regarding your symptoms of nausea, headaches, and gastrointestinal discomfort, these can be attributed to hormonal changes associated with your menstrual cycle. Many women experience premenstrual syndrome (PMS), which can include symptoms such as nausea, mood swings, headaches, and digestive issues. These symptoms can sometimes be confused with early pregnancy signs, but they are often related to the hormonal fluctuations that occur during your menstrual cycle.

Since you have already taken multiple pregnancy tests, including one after your period started, it is unlikely that you are pregnant. Home pregnancy tests are generally very reliable when used correctly, especially after a missed period. If you are still feeling uncertain or if your symptoms persist, it may be a good idea to consult with your healthcare provider. They can perform a blood test for pregnancy, which is more sensitive than home urine tests, and can also evaluate your symptoms to rule out any other potential issues.

In summary, based on your description of your menstrual flow and the negative pregnancy tests, it appears that you are likely not pregnant. However, if you continue to experience unusual symptoms or have concerns about your menstrual cycle, seeking medical advice would be beneficial. Your healthcare provider can provide reassurance and help you understand your body better, ensuring that you feel supported during this time.
