I wouldn't worry about it...I didn't start showing with my sixth or seventh month with my first son. But this time around I've been showing since I was four months
My stomach still isnt hard or really huge. Im 24 weeks...only time ppl know im preggo is when i wear my maternity pants bc they help give me sum roundness. Otherwise i look like i need to go do some crunches lol
Give it a few weeks. I always "pop" about 20 weeks. relish in not needing maternity wear yet!
