Hi, my girlfriend is 18 and she is experiencing dizziness, feeling like her room is spinning, and vomited. I am almost completely sure she can t be pregnant because I ve only penetrated her twice for a few seconds and both times were with condom and that was it, it s also been several months since the last penetration happened and she s taken a test before that and it came out negative. I need help because she said she only feels dizzy and nausea and would like to find out what it could be. Thank You for any help given.
