I am a 20 years old girl . I have my periods after 4 days of sex . But it is on the correct date of my menstrual cycle after 28 days. I usually have fever and vomiting during my periods. This time also I have the similar kind of fever and vomiting. But this time since it is my first intercourse I have a doubt that I may be
pregnant. I have no other symptoms. Please help me to make my mind clear
