Advice

Ok ladies I need some advice. My mum thinks I should go to the Dr to be checked out but I don't know. So starting Sunday I've been having some pretty bad cramps that are unusual, like something I've never experienced before. It feels like really bad gas pains but it's cramps I can feel it coming on it gets really "tight/painful" then it passes it's located in my uterine area but also simultaneously in my lower back. But it's bad enough to take my breath away. I've had kidney stones and ovarian cysts before and kid rate that pain an 8/9, this pain I'm having is about a 5. I've been spotting since Saturday on and off. I've been getting little dizzy spells. And I'll crave a big meal, make it, eat about a quarter of it and no longer want it. I'm tired and cranky. I have PCOS and have been trying to get pregnant for over 2 years so I know it's not that I'm pregnant. Hasn't happened ever so it's not gonna now. I'm 36yr old. Has anyone ever experienced these issues? Anyone with info or advice is very much appreciated. Thanks💗💗💗
