How many days of pregnancy can be detected through a serum beta hCG test, and how accurate is it? Is there any other test to confirm pregnancy?

Serum Beta hCG test can detect pregnancy as early as 10 to 12 days after conception (around the time of missed periods). It is highly accurate for pregnancy confirmation and more reliable than urine tests in early days. The level of Beta hCG roughly correlates with pregnancy weeks, but ultrasound is used to confirm gestational age accurately. For further confirmation, a Pelvic Ultrasound (after 6 weeks of LMP) is done to confirm location and viability of pregnancy. You can book a Serum Beta hCG test if you suspect pregnancy for early confirmation.

I am 28 years old and just took a pregnancy test, which came back positive. I am feeling very anxious, extremely tired, and drowsy. I already have one child, 4.5 years old. Could you please advise what steps I should take next and any precautions I should follow at this stage?

My friend menstrual cycle is delayed by 1 week. She has had consistent unprotected sex, with the last instance 2 days ago. She recently had a fever for a day and now has a cold and cough. She took a pregnancy test, and it came back positive. Could this test be wrong? It is an unwanted pregnancy, what options does she have?
