I just had a really really sharp stabbing pain which felt like it was in my vagina and all the way up to my lower stomach and then kinda spread out to the sides. It honestly felt like the insides of my vagina were ripping. It came on reply quick and it hurt so bad. I couldn't even stand up straight. I'm really worried and don't know if I should go to the hospital. I'm 20 weeks today btw. Is this normal? If not, should I go to the hospital?
