OMG I an so bloated

Ok so this is my 3rd pregnancy never experienced this bloating before. With my first 2 I didn't show until about 20 weeks. I am only 5 weeks!!! Is this normal! To top things off we haven't told anyone not even the kids. My husband has this thing he wants to make sure everything is ok and have the first ultrasound. I am so excited I want to tell the world but I'm bitting my tongue for him, but now look at my stomach how am I going to explain this tomorrow at the family BBQ?
