We have been trying to get pregnant for 4-5 months now and I recently went to the doctor and was astonished at my weight. I have recently joined weight watchers and I love it! But my husband still wants to actively try to have a baby. I'm concerned that if I get pregnant that I'll become too overweight for my size and it could harm me and the baby. I'm 5'2 and 190 pounds. Can I still lose unhealthy fat while pregnant?
