I started my first and third pregnancies at 230 pounds. I am not sure on my second one where I started but I was 271 the day he was born. They are both healthy, normal boys. I did end up with high BP and pre-eclampsia symptoms with my first two. THis time I am hoping to avoid it by eating a healthier diet, walking, and drinking lots of water. You can do this!! I walk about 45-50 minutes 3-4 times per week. I logged my food up until about a month ago but I am doing fine without it currently. Trimester one I lost 8 pounds, trimester two I gained them back, and now I am where I started and will probably gain a few during the third trimester. Congrats to you!!
