I am 25 weeks and my belly button hasnt popped nor did it ever did with my first child and my stomach isnt hard. Everyone different
Be careful what u wish for ur Jus lucky I felt the same way at 18 weeks by the time I was twenty my belly bump decided to show it will happen don't worry hun
My belly button never popped with my dd and I never really had symptoms. I am 13 + 5 with this one and my only symptom has been breast tenderness. You are just lucky :-)
Ur still early... baby is still small... if ur a ftm like me it could take until 25+ to start showing but everyone is different
