Weight pain

As

So I’ve always been pretty worried and conscious of my weight.. I’m 24 yrs old, 5’7 and weighed approx 140 lbs before I got pregnant.

Last time I weighed myself before being pregnant was in August.

I’m 6 weeks pregnant now, I weighed 146 on Tuesday and just weighed myself again tonight I’m 149lbs....

What is the average weight gain for pregnancy... should I be worried ?? I don’t eat unhealthy and I don’t eat more often than I should be. (Two small meals a day as I’m usually busy feeding and running after my 2yr old)

My first pregnancy I was 118lbs when I found out I was pregnant and i don’t remember what I weighed when she was born.

Basically wondering what others are gaining, if this is normal or should I be worried ?
