I'm 17 and I had protected sex two months back on 6th of December 2017 I bled heavily that whole nights but later it was normal. I also went to the doctor and had ultrasound to check if I was hurt inside as I was worried if it was bleeding due to losing virginity. After that sex I had normal periods starting on 7th January 2018 and today I'm nearly 10 days late with my periods. I'm extremely worried. I'm confused as I already had period once and that sex wasn't that long it was just 5min and I checked the condom properly it wasn't damaged. anyone tell me if I could be pregnant or not? I seriously don't want to I'm 17 and I'm starting with my exams tomorrow. I'm worried what to do. Please help..!!
