No bump at 19 weeks

Hey ladies!😊

I am currently 19 weeks and no sign of bump . did anyone else not show so late ? I have anterior placenta so cant feel bubs either. has anyone else had this i just wanna no bubs is algood and i find myself always worried about bubs rather then enjoying ths pregnancy. I had a scan at 15 weeks and he was fine but havent bought anythng until i see hm at my 20 weeks. I am just so scared of doing somethng wrong or somethng happening x
