About a week ago me and my boyfriend were in bed and we got carried away and he put his penis inside me without any protection it was only for about 2-5 seconds but it also happened again and he has to take it out and cum. Now it became a week later and I began to get very sore breasts and they were very tender and was starting to get uncomfortable feelings in my lower stomake. I took a test at school, my friend gave me a test but it was a very crap one that told me to put my pee in a cup and leave it in there for 10-20 seconds but I didnt have a cup so I just peed on it. We waited for 3 minuites and it said that it was positive. Im really scared but I didnt do the test right and it was a high proven one. Please help me what do you think?
