No way to avoid it. It has to do with the uterus getting bigger and moving. Just drink lots of water. I actually had to by sone maternity clothes at 7 weeks because my clothes wouldn't fit I was so bloated. I deffinetly love the baby bump way more then the bloating.
I have heard peppermint helps... Not sure though.
I'm 7w 2d and my tummy has bloated to being 2 times bigger! I seriously feel like I'm 6 months because my tummy has bloated so much!
I'm glad im not the only one haha...I haven't gained any weight but it just drives me nuts feeling so big when I'm not far along at all
