Squishy stomach uggghhh

So I am a little over 17 weeks and even tho my stomach is sticking out its not a hard round form??? It's squishy like I'm just fat??? I am 5'5" and weighed 152 before preggo but I didn't have a gut at all I was trying to lose 10 lbs before I found out so I had more weight than I wanted but was very fit..I still exercise now cardio and toning...I won't wear anything tight fitting cuz I get the looks like I have a roll ...I felt the baby move last night but having the squishy stomach does make me worry a bit??? Just curious if anyone else has this issue??
