Pregnancy Fears

so when i got pregnant with my first daughter, i was 21 and very overweight. i peaked at about 225 shortly after she was born. since then i have lost over 100 lbs, and here i am pregnant again at 30. its still very new(5 weeks) but im worried about packing on the weight with this pregnancy. im not completely obsessed and im just concerned with growing and a healthy bean. but i kinda wanted to vent as im sure many ladies here have similar fears or worries and im so hormonal im kinda just looking for others that understand 😰😥😨😓
