My girlfriend and I fooled around on March 5, but we did not have sex. We humped naked (no penetration) while I was wearing a condom, and after that, she put her clothes back on, gave me a blowjob and made me ***.
Her last period was on February 13. Her cycles are irregular. Recently, she has been stressed out by the fact that she could be pregnant. I keep telling her that she is not. Not only that, but it's our last month at school, and the work is piling up for the closing ceremonies.
Just a few days ago, she has gotten symptoms of her usual PMS like migraine.
What would be the chances that she is pregnant?
