Pcos sucks

Na
So I have pcos and my last period was May 21st. I tested a few weeks ago and I got a negative :( I have cramping, sore breasts, mood swings, no spotting, no sign of AF whatsoever but I seriously doubt I can be pregnant. Just so frustrated with my body and this stupid disorder. It's to the poor that I'm scared to retest because seeing another negative will be my undoing. :/ anyone else going thru what I'm going through??? Please tell me this gets better because it's starting to take a toll on me.
