A.B.
I agree with DeeW,
I too had to ask my doctor to place me on prometrium (sp?) during pregnancy number 6. My first child was a natural vaginal delivery. Baby two was C Section. Baby three was a VBAC, same as baby four, THEN I had a miscarriage, and then I discovered I had thyroid disease. As soon as my thyroid was level a month and a half later I was pregnant with baby 6. My hormone level was dropping and I asked the doctor to place me on prometrium. It kept her in and later I had complications due to pneumonia, I had to be in the hospital for the last five months of the pregnancy b/c the pneumonia caused pre term labor. She had to be born by emergency C Section at 36 weeks (my doctor made me keep her in and let me have her at exactly 36 weeks because my body was so tired) but didn't spend a night in the Neonatal ICU.
Try checking your TSH level first though. My endocrinologist's specialities are: Endocrinology & Metabolism, Obstetrics & Gynecology, Reproductive Endocrinology & Infertility, and she told me that the thyroid dysfunction is one of the many reasons women may have miscarriages and it is not screened for enough during pregnancy or otherwise. It's a simple blood test. I had no other symptoms other than fatigue, but I was also working 18 hours a day, so would wouldn't be tired with that kind of schedule?
Best of luck to you. I am very sorry for your loss, I remember the hurt, and I do pray that if it is your desire, that you will have another baby again with a healthy pregnancy and baby.
