Hello, I have Crohn s disease but the past 5 days I ve been experiencing bad nausea, tiredness, cramps, diarrhoea, bloating but loss of appetite. I m not sure if I m pregnant, I last had sexual intercourse 5 weeks ago but I do have the contraceptive injection. Im hoping it s just a bug but I may have to do a pregnancy test to be on the safe side. Help!
