Thats absolutely fine dont worry.. you will show up after 24weeks

21st week 4days...fetal weight was 342 gms+ or - 31 gms

What is the fetal weight in recent scan??

Usually the weight gain is not a concern as lonng as the baby is growing fine. Ans usually some women staft gaining only in the 3rd trimester. Check your bmi,in case you are underweight perhaps you may require better nutrition. My weight started increasing only in the end of 6th month but my doc wasn't worried as my before pergnancy weight was not a concern. 42 seems to me underweight.<br> I am tagging an expert, she will be able to help better. Don't worry and tkcr. Your gynac will alarm you if anything needs to be done.<br> <b><span style="color:#3B5998;"> @616d5a27c1b4770013bcb718 </span></b>
