What does 4 weeks of pregnancy look like?

I just got a faint positive test and I think I am around 4 weeks pregnant. Is it normal to feel a bit of lower back pain so early, or should I be worried? I am very new to this and feeling a little nervous.

At 4 weeks, the pregnancy is very fresh and physically you look completely normal. You might feel slightly more fatigued than usual during office hours or experience mild breast tenderness. It is best to confirm with a home test kit and schedule your first doctor's visit.

For me, 4 weeks felt just like PMS with some light cramping and extreme tiredness. I didn't have any morning sickness yet, that started much later. Everyone's body reacts differently at this early stage, so don't worry if you don't feel much.

At 4 weeks, the embryo is about the size of a poppy seed, so there are no outward physical changes. Hormonal shifts are beginning, which might cause mild symptoms like mood swings or fatigue. Please consult a gynecologist to start your prenatal vitamins like folic acid.

When my wife was 4 weeks pregnant, we immediately focused on keeping her stress levels low and monitoring her health. Since she has a history of high BP, we started regular checkups early. It is a crucial time to establish a healthy daily routine.
