Hi My Name Is Kamakshi And I Am Afraid That

Hi my name is Kamakshi and i am afraid that I might be pregnant. 4 or 5 days ago i have been raped and after that i have been going through headache and dizziness and i am not able to do any work. My friends are trying to comfort me by saying it might be because of climate change. But i want to know what it is. so when can i take the praganews test?
