I've had it since just before I got pregnant, and saw my Dr at the start who gave me anti-biotics, didn't work, I still have it now so went to the Dr's again on Wednesday and have more anti-biotics and paracetamol. He said if it's still not budging I will have to go back and we will have to see about an X-Ray but they don't recommended X-Rays in pregnancy so don't particularly know what will happen :s x
