Welcome to health care magic.
As you take REGISTRONE for postpone of periods for 10 days, there is hormonal
imbalance and period may be delayed (not get in date).
A positive pregnancy
test gives 2 clear purple line.
If you think of pregnancy (having unprotected sex),you can do blood test
for HCG for confirmation.
Check the result.If positive,consult with gynecologist.
Other things you have to know for delaying period like Stress, Thyroid problem, Over wt, PCOS etc.
So need to do yoga & meditation
to avoid stress. Take healthy diet.
All the best.
