What do my symptoms mean?

Hi girls, so the past couple of weeks I've been really bloated all the time, struggling with fatigue, nauseous and I keep needing to go for a wee😂 Does this mean anything? I've looked on google and possibilities are Irritable Bowel Syndrome, coeliac disease, and even pregnancy😩 
Can any of you help a girl out? Any ideas what this could be? Any advice would be sooooo appreciated!
