I am 33 and 27 weeks pregnant so just starting my third trimester. I am a big girl about 320 lbs right now. Every thing is going perfectly so far for this pregnancy. I haven't over gained yet just 10 lbs so far this pregnancy but my dr wants me to focus on losing as much as i can before birth. I find this very stressful . i keep feeling like im failing because so far I've only been able to lose 2lbs in a couple weeks. Has anyone successfully done this? Any tips?
