I was cuddling with my girlfriend and later on I inserted my penis 2-3 times without protection but did not ejaculate. Maybe I had a precum. She did not take any contraceptive. Also this was on 14th May. She got her periods 15 days later on 4th June as it was supposed to be on 20th May. She also have irregular periods. So does that mean she is pregnant? If so then what are the solutions. I am confused. Please help.
