Hey hun, first of all, try and calm down, I know it's scary, but things are never as bad as they seem. These things happen and I am pretty sure your parents wont kick you out. You are going to have to take the test hun, thats the only way you are going to find out, other than that you will have to go to the doctors. I was the same age as you when I fell pregnant with my first (birth control failed) I was terrified too, and it all turned out ok, my first is coming 8 next month. Try not to panic too much ok? If you are pregnant you will just have to let your boyfriend know and you guys will have to tell your parents like grown ups, if you try to hide it they will take it worse. Anyways, I hope I helped a little at least, good luck to you hun and all the best :)
If you have missed your period, take the test so you know one way or the other. I have connections with crisis pregnancy centers and others. If you ARE pregnant, I can help you find a good home for your baby. There is also a good chance you can get other help for while you are pregnant. Take the test and let me know what the result is. I can be here to help you through this whether your family is or not. Feel free to message me if you want to.
