I had sex with my boyfriend unprotected and not for long but still and the last few days I've been getting bad cramps and when I urinate it stings and at first I though it was uti but then there's blood that comes from my vagina, I also had my finger up there to see if everything was fine but I felt this large ball kin of thing that felt like it was my cervix opening except it has never been there before So I'm really scared there's something wrong with me and I don't want to ask my mum incase she thinks I'm pregnant or if It turns out I am I would be dead I don't know what to do
