Gaining in early pregnancy

Erin

Hi ladies. I’m 33, 5’6.5 and recently became pregnant with my third child. When I conceived I was 110.5lbs. I’m now 5 weeks in and I’m already at 113! I haven’t been eating more, in fact I’ve been eating less and healthier than ever and working out because I’m terrified of gaining weight that I can’t lose after this baby.

I struggled with anorexia for about 10 years and pregnancy is always an extra difficult time for me :/

I’m freaking out because I’m gaining for no reason (gain should really only start in earnest in 2nd trimester, right?) have any of you experienced unexplained weight gain like this in early pregnancy?? Help :(
