Really worried?
Answers: I think you should be in motion to your doctor. Very soon. Not to worry you even more.
Is in attendance a chance that you could be pregnant?
If so, near is something that a friend of mine had call an ectopic pregnancy where the egg doesn't clear it down into the womb and gets stuck contained by the phallopian tube.
If you there is positively no chance that you are pregnant I would still pop in your family doctor to discuss this.
When your body go through a change.. (like the flu) your length will go wacky... normakl see your doctor at hand could be something else going on there.
umm..sounds resembling a kidney infection. blood in your pee, confusion, nausea, vomiting, sharp pain contained by abdomen (where your kidney's are) move about to the doctor
it could also be an ovarian cyst, or possibly an ectopic pregnancy- all can own the same side effects- but please budge to the doctor!
it also helps to drink cranberry liquid, and more water
