Hi

For the past 2-3 weeks I've been having terrible abdominal pain, it started in the right lower abdomen (between hip and navel) and now it's spread all over the lower abdomen. I've also been feverish, nauseated, urinating frequently and constantly tired. I saw a doctor at the beginning and he thought it might have been my appendix but he took a urine sample and 2 blood samples and they came back normal (though something in my blood was high for my ages, he's looking into it).
The pains got worse so he passed me on to another doctor and she thought it could possibly be an ovarian cyst. I was scheduled to have a swab test with her but I got my period the night before my test, 4 days early, which is odd because I've been on the pill for about 3 or 4 years now and it's always been rhythmic. I went anyway and told her I couldn't have the test so I could reschedule.
During my period I didn't feel much, even on the pill I have to take a lot of paracetamol to feel alright. My period finished 2 days ago and now the pain is much worse. I saw my doctor again for the swab test and she says there's no sign of infection. It hurt when she was doing the test and I've been in pain during sex ever since I lost my virginity. She put me on the waiting list for an UltraSound a week ago, still waiting for an appointment.
She said she thinks it could still be a cyst, or possibly endometriosis

Can anyone shed some light on the situation for me? I'm getting rather worried
Thanks

Lucy
