my best friend is 16. her boyfriend is 20. she has had intercourse with 5 to 7 people. he on the other hand has been around the block a couple times, if you get what im saying... she could be pregnant with his baby. she's not quite sure. they have been together for about two weeks now. i heard it takes about three or four weeks to find out if you are pregnant or not. her boyfriend is saying he is having trouble urinating, and burning when he does urinate and testicle inflammation. he thinks he might have a disease and is blaming it on her. what could this be???
