Opinions...??

Shannon
Hi all this is probably crazy but I want to see all your opinions. No hate please!
I'm 7 weeks 4 days, but I feel like a whale, I feel extremely bloated more than normal, I feel really nauseous 24/7 and after being awake for 2 hours I want to crawl back in to bed and sleep the whole day! 
I'm always tired, nauseous, very emotional and highly bloated.
I keep dreaming that I'm having twins, same dream almost every night. 
I was wondering if it is my self conscious telling me I'm having twins or I'm just going to have a big baby??? 
If it helps this is my first baby.
Thank you all for any opinions or advice 😀 x
