Am sorry to hear about your miscarriages. I just feel I want back what I lost and am afraid I will lose this one aswell! I really hope everything will work out for you and your baby.
Every miscarriage is different. I have had 3 and each was different with the exception of a fever and migraine. One hurt so badly I couldn't move, another I was so mad about everything I locked myself in my room to avoid screaming at my husband and making things worse, and another I ate constantly. Just do what feels right for you and your s/o and take it easy for a few days.
