My freind and her bf had some fun that night. But she is saying that they didn't do proper sex, his penis head just touched her vagina. He was trying to put that in for couple of seconds but the penis was not getting in as she was a virgin. Then she refused to do so and they stopped. Her date of periods is 13th of Feb. Today is 26th March. Still she is not getting her periods out. Also she is suffering with some health issues. She did do pregnancy test with the help of pregnancy kit and it came out negative. But still she is not sure. Because she did it like, she stored her morning's first urine in a bottle and later on at noon she brought a kit and did a test. The test came negative but she is facing issues with her health like vommiting, weakness, headache and her periods are not getting out too. Is she pregnant?
