Thanks for your query.
herb Vitex is one of the most powerful herbs for women's fertility and menstrual health.
It will increase your chances of pregnancy
by correcting hormonal
Pregnancy test is 95% sensitive when it is done on the day of missed periods and 99% sensitive when it is done 1 week after missed periods.
In your case since your pregnancy test done ten days after missed periods is negative, less likely you are pregnant.
I recommend you to get a transvaginal ultrasound
done to detect early pregnancy.
Other causes of missed periods are stress, ovarian cyst
and thyroid problem.
You need to consult with a Gynecologist if pregnancy test is negative.
Hope this helps.
