I went to the doctors because i thought i had a urine trapped infection i was having bad lower back pains, sore vagina and it hurt when i went to wee. The doctors took a urine sample and said they had to test it because they weren't too sure what was wrong. They proscribed me anti biotics and it stopped the pain  when i wee. I got a phonecall from the doctors saying they didn't know what was wrong and if i was still experiencing symptons i had to go back to the doctors asap.I didn't feel ill however a day before my period i had sharp lower back pains and blood spots in my urine but not in my underwear. I felt really sick and i wasn't meant to start my period for another two weeks so i didn't know what was wrong and then the next day my period came. My periods are now irregular and i am still getting lower back pains and i don't want to go back to the doctors because i am too scared.
