You need to see a health care professional immediately.  Being proactive now is better then reactive later.  The best ways to get answers to your questions, that will help you take away the pain and prevent complications, is to see a good O.B.G.Y.N.   If you have a family doctor, see or call that person and get them to recommend more than one physician.   Visit this specialist, and if you cannot talk with them openly and comfortably, then choose another one.   It’s not a good idea to just pick someone from a phone book.  Ask family members and friends too, whom to see.  Don’t assume the worst case scenario.  Don’t look on the net for symptoms like yours, and then panic.  Get answers, and get them now!!
