Confused! Help?

Tabitha • I'm 24 and pregnant with our first! A baby boy! Hubby and I are thrilled!
So I am 7 weeks today and all of a sudden have a noticeable round tummy! My hubby saw it and was all "wow you really are pregnant!" Which is sweet, cause he meant it in the best possible way but I know we aren't supposed to be showin for a while! I know what bloat is and this feels different. It's very hard and not squishy like bloat! And now I hate wearing jeans cause it is so uncomfortable and sometimes hurts! Help? Is this normal? This is our first baby!
