15 weeks and a day.

Hi y’all, I’m 15 weeks and a day pregnant, I have no bump or at least I don’t think I have one, I was heavier to start with when I got pregnant so if I had one I would be able to tell. Also my belly isn’t hard at all, secondly I’m having hardly any symptoms not even kidding. I’m not sure if should be worried or not did any of you experience this and is this normal. Thanks alot!
