Too much weight

Naysha • Due may 7 baby boy Josias 💙👶👣
My pre-pregnancy size was 140. I am now 29 weeks and weigh 178. I'm a FTM and would like to see if anyone else went through this. I'm feeling concerned that after I give birth I'll be way overweight. Any tips or ideas I know I'll gain more weight but how much more is healthy?? Please help :(
