Unless your skills are tip top, the chances are that you will have had a traumatic tap before (studies suggest up to 40% of lumbar punctures). Blood in the CSF on lumbar puncture can be a sign of a subarachnoid haemorrhage but more commonly is due to a traumatic tap (if the number of red cells in consecutive samples remains the same, it’s likely to be an SAH, but if they reduce then it’s likely due to a traumatic tap).
