I have been with my girlfriend for 7 months now. One week ago we had sex and the condom slipped as I was pulling out, I have no idea if it leaked. She is on the pill but had not taken it in around 6 days as she did not have time to collect the prescription. Just to be sure she took plan b the evening after. She had just finished her period the day before this happened. She is assuring me that she is not pregnant, but to be sure I made her take a test today, which was negative. I know it's probably too soon to be taking a test but I'm worrying because I have to leave the USA for 10 months on the 7th July, just after her next period is due and cant leave if something is up. I have been told by many people that I am over reacting but I just cant help it. Really, what are the chances she is pregnant ?
