I'm so sorry you are thinking the worst!Cervical cancer is not painful,has no symptoms unless extremely advanced.Pregnancy,well,you would know if your cycle is late.You did not mention that,but if that is possible,you really do need to see the doc asap.Sometimes if you have vigorous sex,you can have some internal bruising and are sore for several days afterwards.The pain you are describing seems more intense than that.I would see my doc,tell them you are in a lot of pain.That should get you in sooner.Hope you feel better soon!Patty
