On 1-14-13 myself and this girl were messing around, she gave me head and I finished in some napkins. After this we talked for a bit, before I was leaving I put my hands down her pants and rubbed the outside upper portion of her vagina, which I did not even reach her clit. I am concerned that this may have caused pregnancy. Exactly one week later on 1-21-13 she said she threw up after eating. This happened again on 1-22-13 and 1-23-13. Today, 1-24-14 she said she felt back to her normal self with no signs of nausea/vomiting. I do not know if this is morning sickness or possibly the flu. Even though its a bit early, she took a pregnant test which came out negative. Her last period was on 1-7-13 and her next period should start around 2-4-13. She has regular cycles. Any information/input on this would be greatly appreciated. Thank You!
