Delayed menstruation?

Hello doctor, I would like to ask about my menstrual cycle last month, which was from June 17 to July 1.
I had unprotected intercourse during that time, but my period has not arrived yet, and I am hesitant to take a pregnancy test.
If I am indeed pregnant, how far along would the baby be?

More Info

When it comes to understanding late periods and the possibility of pregnancy, it’s essential to consider several factors, including the timing of your menstrual cycle, the nature of your sexual activity, and the typical signs of pregnancy. Based on the information provided, it seems you had unprotected intercourse around the time of your expected ovulation, which could lead to conception.

To determine how far along you might be if you are indeed pregnant, we typically calculate gestational age from the first day of your last menstrual period (LMP). If your last period started on June 17, and you have not had a period since, you would be approximately 4 weeks pregnant as of today (assuming a regular 28-day cycle). This means that if you were to take a pregnancy test now, it would likely show a positive result if you are pregnant, as most home pregnancy tests are sensitive enough to detect the hormone hCG (human chorionic gonadotropin) about a week after a missed period.

If you are concerned about the possibility of being pregnant but are hesitant to take a test, it might help to consider some early signs of pregnancy. These can include missed periods, nausea or vomiting (often referred to as morning sickness), breast tenderness, fatigue, and increased urination. However, not all women experience these symptoms, and some may have them even when not pregnant.

Regarding your concern about the size of the baby, if you are pregnant, the embryo would be very small at this early stage, typically measuring only a few millimeters. At around 4 weeks, the embryo is still in the early stages of development, and it is too early to determine any specific growth metrics. Ultrasound measurements and fetal development assessments are usually performed later in pregnancy.

If you suspect you might be pregnant, I would recommend taking a home pregnancy test for confirmation. These tests are widely available and can provide results quickly. If the test is positive, it would be wise to schedule an appointment with a healthcare provider for further evaluation and to discuss your options moving forward.

In summary, if your last period was on June 17 and you have not had a period since, you could be around 4 weeks pregnant. Taking a home pregnancy test would be the next logical step to confirm your status. If you are pregnant, early prenatal care is crucial for monitoring the health of both you and the developing fetus. If you have any further questions or concerns, do not hesitate to reach out to a healthcare professional for personalized advice.
