Understanding menstrual irregularities and early pregnancy signs can be quite complex, especially when considering the various factors that can influence a woman's menstrual cycle and the early signs of pregnancy. Based on the information provided, let's break down the situation and address your concerns.

1. Menstrual Cycle and Irregularities: A typical menstrual cycle lasts between 21 to 35 days, with the average being around 28 days. However, cycles can vary significantly due to stress, hormonal changes, health conditions, and lifestyle factors. In your girlfriend's case, her last menstrual period was from February 12 to February 18, and she had unprotected intercourse on March 3. If her cycle is regular, she would be expected to ovulate around mid-cycle, which is typically about 14 days after the first day of her last period. This means that the timing of intercourse could potentially coincide with her fertile window, increasing the likelihood of conception.

2. Light Spotting: The light bleeding observed on March 15 and 16 could be implantation bleeding, which occurs when a fertilized egg attaches to the uterine lining. This type of bleeding is usually lighter than a normal period and can be brown or pink in color. However, it could also be a sign of an irregular menstrual cycle or other factors unrelated to pregnancy.

3. Pregnancy Testing: The pregnancy test taken on March 17 showing a single line indicates a negative result. Home pregnancy tests work by detecting the hormone human chorionic gonadotropin (hCG) in urine, which is produced shortly after a fertilized egg implants in the uterus. If the test is taken too early, it may not detect hCG levels, leading to a false negative. It's generally recommended to wait at least a week after a missed period for the most accurate results.

4. Symptoms of Early Pregnancy: Early signs of pregnancy can include missed periods, nausea, breast tenderness, fatigue, and headaches. The slight headache your girlfriend experienced could be attributed to various factors, including hormonal changes, dehydration, or stress. It's important to note that headaches alone do not confirm pregnancy.

5. Next Steps: Given the circumstances, if your girlfriend's period does not arrive as expected, it would be advisable for her to take another pregnancy test a few days later or consult a healthcare provider for further evaluation. If she experiences any unusual symptoms such as severe abdominal pain, heavy bleeding, or other concerning signs, seeking medical attention promptly is crucial.

6. Lifestyle Considerations: Regardless of the pregnancy status, maintaining a healthy lifestyle is important. This includes a balanced diet, regular exercise, and managing stress levels. If pregnancy is confirmed, prenatal care becomes essential to ensure the health of both the mother and the developing fetus.

In conclusion, while the signs and symptoms can be indicative of pregnancy, they are not definitive. The best course of action is to wait for a missed period and retest or consult a healthcare professional for a more accurate assessment. Understanding the nuances of menstrual cycles and early pregnancy signs can help alleviate concerns and guide appropriate actions moving forward.
