Small bump 22 weeks..RANT

Im 22 weeks and have no bump.i wasnt a skinny woman before just belly looks like ive had a good meal.Im still in same size jeans and my tops havnt changed in size according to family and friends somthing serious may be up i need go get checked out even though at 20 week scan he was measuring ahead.People keep telling me how pale and ill i look and how pregnancy is taking its toll on me..i feel fine loads of energy my partner still says i look beautiful its just pissing me off how they keep commenting like this

Sorry for the rant :(
