Weight gain

L

Soo I’m 13 weeks now and I guess just started the 2nd trimester? I keep reading different things about when it starts. I gained 4 lbs first trimester and am worried it’ll pick up even more than it should now. I want so badly to have a healthy pregnancy and only gain what’s needed but I’m nervous it’s not going to happen. I worked so hard to stay in shape before and stay lean. Anyone else feeling the same way?
