Advice please

Idk what is going on I don't think I'm pregnant but that's all that I can think that could be going on. I just want to sleep all the time. My moods are horrible my boyfriend has been good at dealing with me with them but has told me I have been very mean. I am always sick to my stomach. I have cramps and I have been having them basically non stop for over the last two weeks it started with my period but that stopped after 6 days. I have heart burn at least very other day. And I have intense bloating to the point I look 7 months pregnant and it hurts so bad and I can't stop farting that just started over the last couple days. I'm on birth control plus I also have pcos. Maybe I just have a cyst acting up and making me feel like shit but the birth control is suppose to help with that. I seriously glue myself on the couch and just sleep everything away I sleep for 13 hrs at a time and wake up every few hrs and just roll over and go back to sleep. I had cramps so bad it felt like my stomach was moving with the cramps even.
