test results

Hello, ive already wrote on here recently and thank you to those who reassured me it really did put my mind at ease. However, the Dr called me today to advise that they'd had some results back, i was really hoping that I had an infection at worst that  causes my symptons and would be cleared with a course of antibiotics. ..no! All infection tests were back fine. I suppose this has caused me to fret a little more now...I'm constantly suffering with period type cramping pains, the bleeding can be red blood or simply just a brown discharge ( Sorry for the info) but I just don't know what to think. I am a scheduled to have an abdominal scan aswell as a transvaginal scan on Sunday morning and should get the results of my smear early next week. I'm not one that can wait for answers at the best of times never mind when it comes down to health!
