Thank you for the question and thank you for visiting our site. I am so sorry about your loss! First, it is important that you review with your doctor all of the possible causes of this loss. Some of them, such as diabetes, could lead to irregular periods, fatigue and bowel related problems. Your symptoms are not specific and could be anything from diabetes, as I mentioned, to other common problems such as thyroid disease. Schedule a visit with the OB/GYN or OB Provider who helped you through this loss and see if they can offer assistance and guide you on labs that might help to sort this out. I hope that this helps and good luck! Dr. Raichle
