Just looking for opinions before my appointment next Tuesday!

My period is now 53 days late, I have on & off cramping on both sides, I’m super bloated majority of the time, my hair is falling out like crazy.. especially when I shower. I feel like I have all the pregnancy symptoms, but every test is negative. I have 3 kids and I’ve never been told anything was irregular on any of my sonograms or PAPS. After doing some research, I’m starting to think I may have PCOS. If you have it, does this sound like something you experienced? Thanks!!
