In the morning low urinary stream/ enlarged prostate?

This one is for the experts here. Since a few time my urinary stream is weaker. Less pressure. After waking up in the morning the stream is weakest: slow, low pressure and divided somehow.
No pain etc.


I am male. 30 years old. Is that a symptom of an enlarged prostate? I have been to the doctor. All tests (incl.x-raying the urethra with contrast medium etc) showed no anomalies.

Looking forward to hearing your thoughts.
