A few months ago my OB/GYN did some blood work and said that he thought i might have CAH. He said that he would have to call a specialist to find out more info. The specialist told him of more blood work to do. He said that he doubted that i had it since it is considered a rare thing. He did the blood work but sometime in there i got pregnant so he said the blood work would not be accurate. he said that we just needed to focus on the pregnancy for now and didn’t say anything else about my hormones. I am about 8 wks pregnant now and have been bleeding the last couple of days. The Dr. believes i may be having a miscarriage. Are miscarriages common with CAH? if so what can i do the next time to prevent one?
