Kimberly • I`ve been trying to conceive for 12 years in my marriage and have loss two babaies I`m on the edge of giving up please help!
Hi everybody my name is Kimberly I've been married for 12 years to my wonderful husband Fredderick. I have diabetes and I've had lots of other issues has well. We have been trying to conceive for 12 years. A few years back I was 217 pounds and I started working out and, got down to 172 pounds which was great and, I fell good about it. Then I found out I was prego. It was finally happening for us. Until I when to the doctor and, they told me the baby was not alive and then had to take it. It was the hardest time of my life and somedays still is. I when into a depressed state and, now I'm back up to the weight of 192 pushing 200 pounds. I'm afraid that if I try again it will happen badly for me all over again. I would love to have a baby but there is a fear. I've been trying and still nothing. Can anyone help me with some advice please??
