I'm Fourteen Years Old And I Accidentally Had Sex. My

I'm fourteen years old and I accidentally had sex. My mother doesn't know and I thought I was safe but the condom broke . This was around 5 today . I haven't been able to sleep because my lower abdomen has a lot of pain and I am so scared I'm pregnant . I'm also not on birth control . I do not know what to do or what to think I'm freaking out
