Hello nur nabilah
Thank you for writing.
You were helped on this question yesterday morning so your second question was deleted. We ask our readers to post their questions just once.
The answer is the same today - you did not have sex and were fully clothed - pregnancy can't occur.
Sperm would be long dead on your hands by the time you got home.
Grinding with clothes on will not get anyone pregnancy. You can red anything on the internet, it doesn't mean it's true.
Your current symptoms may be a sign your period is on it's way. You cannot be pregnant.
