So I'm 19 + 4 and honestly everytime I've been to see midwife or had a scan or been to drs my urine shows blood in it! I went to drs about 3 weeks ago as everytime I went for a wee It felt like I had been punched in the bladder, not stinging more of a painful ache ( the same when I went for the other aswell! Sorry tmi!) I was told blood and protein in wee again so had urine infection- given antibiotics and went back a week later as no better, another sample done, blood in urine again! Another lot of antibiotics back a week later, went back last week to be told urine had been sent back from lab and was fine ( I have the pain still after going to the loo to the point where I have been crying its that bad and some days it doesn't go away) but urine sample given thee and then had blood in it again this dr thinks I have spd and said it hurts when I go to the loo as there's "nothing to support me" she had a feel around and my bladder feels like bruised!? So it's not an infection, She said she would send urine off to the lab again but wasn't worried and I have just recvd a letter saying tests are back and I need to go and do another, phoned drs and said blood present again!
Sorry for the long post anyone else had blood in urine and no infection any advice or thoughts on what's going on? Just getting a bit worried? I'm not convinced its spd- can't understand why it's just when I go to the loo?!
