CD75 and negative tests

I am CD75 and this is the very 1st time that happened to me for 31 years. I went to the doctor today and he offered me bloodtest tomorrow. I am so worried about it. Maybe I have a problem. 😟 I am so bloated. So big boobs and I have a lot of cravings. In short I eat a lot this past 2 mos.

.......

Is it possible to have a positive in a bloodtest and negative in the PT? Or I have PCOS?
