Hi K.. My pregnancies have been pretty different so far. I weighed more and gained more with my first. Started around 190 and was 255 full term! Lost a lot with Weight Watchers while my son was 6 months to 2 years. You can't diet while pregnant, so I'm off WW, but plan to get back on once I have this baby. This time, I was about 178 starting out, I'm in my 24th week and I'm right at 200 right now. Hoping to keep it under 215 this time, so having the baby and hopefully nursing will get me below 200 right away. Then WW will help me take care of the rest. I also took him on lots of long walks. Once I got below 200, I started jogging, biking, swimming, etc. Any exercise is good, even dancing and roller skating. Keep it fun.
So that's my experience. I'd say go for it. You could wait, but you may never be the perfect weight. Just try to be careful and don't worry about weight loss until after you have the next baby. Good luck.
