Hi Missy79. I can't be sure of course, but I'm guessing what you've got is the bloating that many women get in early pregnancy. If you are at 6 weeks it's fairly unlikely that it's your uterus sticking out at this stage. It's more likely that it's the 'lovely' changes in digestion that pregnancy hormones that create a bulgy tummy thanks to gas! I was kinda excited that I had a little tummy so early but noticed that it kind of came and went depending on the time of day and what I'd been eating.

As for boobs... yep, they can get bigger really fast! Mine hurt like crazy for the first 10 weeks and felt HUGE!

Hope that helps
