Hi ladies I need help,

I was diagnosed with pcos almost a year ago, my doctor did tell me that it was gonna be hard for me to conceive so me, and my partner tried for a few months, but then we stopped for other reasons. It’s been almost like a few months since we stopped trying, but on May 2, It happened again and since then I’ve been feeling weird. My breast hurts. I’ve got stretch marks on my breast, which I’ve never had. I am a chunky girl but I’ve never seen stretch marks on my breast’s….. I’ve been having cramps as well on my pelvis constant cramps, my back hurts, headache, brain fog like I forget things, I’m not hungry but then I get hungry, my breast are sensitive especially the nipple ….it’s weird I have the urge to be clean 24/7 idk 🤷🏻‍♀️ im so confused I took a pregnancy test today but it came back negative I was like okay but I keep having this symptoms… TMI but im also a lil constipated so idk is it pms? My pcos? Or pregnancy?

Any one help?
