If both home urine test and blood β-hCG are negative 12 days after a missed period, pregnancy is very unlikely.
A first-time delay can happen due to stress, hormonal fluctuation, weight change, illness, or approaching perimenopause (common around this age).
What to do next:
Wait another 1 week for periods to start
If still absent, consult a gynecologist for evaluation (USG pelvis,
TSH, hormones if needed)
When to worry:
If periods remain absent for >6–8 weeks
If there is pelvic pain, abnormal bleeding, or other symptoms
At this point, this looks non-pregnancy related.
