PCOS help

So ladies I found out I have PCOS on February 13th and right before that I was feeling mild to light cramps. I still am feeling them and now my period has been missed. Dec, Jan, and Feb my period was right on time but I haven’t seen one this month. I have a dr appointment on the 28th. I’m scared to take a test because I have taken 5 at the beginning of the month. But I’m still experiencing cramps and I’m new to this. Is this regular to feel cramps like this?
