My girlfriend and I have been together for 8 months and have had sex every day for the past 5 days, including today (1/5,6,7,8,9). We lost our virginities to each other but now I'm super paranoid and annoyed that she isn't even remotely worried or caring that she might be pregnant. I need some reassurance because while we were in the missionary position with a condom, I slipped out. So I put it back in, but hard, and without thinking, I hit the top of her vagina and it went in hard, and as it did, I heard a loud pop. I pulled out only to see my uncovered head and I was very paranoid. I wasn't close to coming, but my head was semi-moist at the time. Also, this was the 8th day after the last day of her period, if that makes a difference. Please someone tell me what are the chances of her getting pregnant, as I am scared shitless. Also, what will be early signs of knowing if she is pregnant or not? She's too stubborn to take a EPT...

Thanks
