Early Pregnancy Symptoms

I am still 1 week before my period due date and has been experiencing very weird GI issue and was wondering if this could be an early sign of pregnancy. For the past few days i have been experiencing gassy stomach/flatulence and increase bowel movement (not diarrhea) I usually only have one bowel movement a day but recently it became thrice a day and the stomach felt bloated. Any mummies out there experiencing the same thing?
