Sayang, abdominal discomfort at 11 weeks is quite common, your body is changing so much, but the persistent pain combined with the bloating and shortness of breath does warrant a quick check-in with your doctor, just to be on the safe side and rule out anything else. In the meantime, smaller frequent meals, staying hydrated, and gentle walks can really help with the bloatedness and gas, though I always find it's better to get peace of mind from your gynae first, especially since you're in your first trimester. Wishing you feel better soon, mummy!
