I lost my virginity 18 days ago and the sex was really short both times since we were worried about being caught. The first time, we used a condom and he didn't even cum and the second time he did a couple thrusts naturally, but didn't cum, and then put on a condom. He did cum that time though... but it was in the condom and neither of them broke. My period was supposed to be yesterday but I didn't get it, but I've never had a late period in my life and I've had it for four years. Also Im in a really religious family so I can't get any tests or birth control :'( Im really worried!!!!!! Please help!!!
