I Had Another PSA Test Done On 3/10/16 And It

I had another PSA test done on 3/10/16 and it remained virtually the same as the test I had done on 1/13/16. I really have no symptoms. I urinate normally except I wake up once at night and it is hard to start urinating. The only thing I noticed that is not normal since the infection is that my semen is still very watery and there is not much volume. I have not been on tamusolin or finesteride since early January because I stopped taking them and my urination was normal.
I am going to get an ultrasound done but it will not be for awhile because the insurance I have is limited to only a few Drs. That are very busy. What are your thoughts??
