1) Get a Serum Beta-hCG blood test : This is the gold standard and will give you a definitive "yes" or "no" regarding pregnancy, completely removing the guesswork of urine test strips.
Next Steps
2) Clinical follow-up : If the blood test is negative and your period still does not start within the next few days, I recommend scheduling an in-person consultation. A doctor may perform a pelvic ultrasound to check your endometrial lining and may prescribe medication to safely induce your period
