Hello dear,
If you are sure that no sperm has entered inside your genital tract, then there is no chance of getting pregnant.
The delay in periods can be due to various reasons such as anovulatory cycles, infection,
hormonal imbalance,
stress, etc.
So, please do not worry.
You can perform a home
pregnancy test using pregnancy kit.
In case of pregnancy, it will give positive results within one week of absence of periods.
And even if the test comes positive, it will be better to consult a Gynecologist rather than trying the methods you have read online to cause a
miscarriage.
Most of the information available online do not have any clinical basis, and following them may cause unwanted harm to the body.
Please let me know if you have any further queries.

Wishing you a good health.
Take care.
