TTC after stillbirth

I had a stillbirth on 12/23/18

My heart aches. I cannot see a baby boy without crying. I was 25 weeks when I lost him. The week before I was diagnosed with gestational diabetes. They have ran many tests and my doctor has found nothing abnormal that could have caused the stillbirth. The conclusion I came up with was perhaps my weight and the gestational diabetes was a factor. I’m 5’3 and I was 240 pounds when I gave birth to my baby. In my previous pregnancies I was always at a healthy weight. I’m now 217lbs. I’m on a strict keto diet and I do body Combat 3 days a week and yoga 3 days a week. As much as I would like to get pregnant right away I refuse to get pregnant overweight. I have 76lbs left to lose to get to my goal weight. Once I get there I will try again. My husband doesn’t have any kids of his own and I really want him to experience fatherhood to his own baby. Wish me luck!
