Ger i totally knw what you mean coz before i had my dear son i am already quite big size as my shoulder is broad n my bones r big so end up i look quite big size for a ger. Especially during the period i am preg with my dear son i was getting more n more fat that i thought i saw a PIG in the mirror. Even after giving birth to my dear son for 6mths i still look so fat BUT i knw we r putting on weight n looking bad for our children. As their mother, we need to have sum sacrifices for them n i believed many of our mothers r just the same too in terms of figure wise.
just tell yourself dont worry so much now as you r preg currently n all you have to do is stay relax + dont worry so much over things that can b solved after you give birth to your #2. just tell yourself after giving birth of your #2 you can slim down but working hard on your diet or even exercise so that you can gain back your old slim figure. you have to tell yourself that you might look fat now is bcoz your preg so it normal which you can slim down again after birth. Been fat now doesnt mean forever but rather if your willing to work hard on your diet which i believe you can regain your old figure again.
dont tink so much n worry so much coz it is really unhealthy for both you n your baby. I believe when your children grows up they will knw how noble their mother is for doing so much sacrifices for them.
