Ladies with PCOS!

Iv been researching a lot on it and have been worried mainly because my menstrual cycle has NEVER been normal one month I could skip another month it could be a normal 28 day other times it could be 4-6 weeks in between periods. the longer it takes for my period to come the heavier it is sometimes it's so heavy and painful I have to change a tampon every 1 - 2 hours and they are the super absorbent but that's not all the time and the cramps that come with that type of cycle are unbearable. Other times its a normal flow. Then some months it's super light or on and off for the week. Sometimes it's really long other times its so short it's like iv had a period at all! I'm probable rambling a lot. I have tried looking online but they don't really give you much. I was just wondering if anyone with it can tell me there experience before I worry my self and get checked out for nothing. Also this is such a silly question but when you have pcos do you get the usually pms symptoms I know everyone's different but the usually constipation tiredness frustration eating everything in site sore boobs etc? Are your menstrual cramps painful do you get them at all? I'm sorry if this post offends anyone I just have so many questions they all seem really silly and I know you shouldn't compare your experiences to other people's but sometimes hearing them is the only way to make your self think there's something wrong or that something isn't
